Hi!
The PC version of the CS 2 includes an English UI, but until you got it up and running you may see a few German words.
The first Setup screen allows you to select the language. On my computer English was automatically preselected and all setup screens were in English. So far so good.
When you start the CS 2 program for the first time, it will prompt for a working folder ("Arbeitsverzeichnis" in German):

This is a dialogue from the operating system and will look different with newer Windows versions (I used XP for the screen shots). I recommend creating a new folder for the CS 2. On my computer, this folder contained 4000+ files and required 141 MiB disk space.
Then you get a warning that the environment will now be prepared for first use:

You will see a progress bar while files are being copied:

If the PC version could not find a real, physical CS 2 on the local network, it will show a warning ("Keine CS2 entdeckt. Es wird nun der Demo-Modus gestartet."):

This means "No CS2 was found. Demo mode will now be activated."
You should close this warning quickly, otherwise more instances of this warning will pop up on the screen. For n warning messages, you will later get (n - 1) error messages when you close the warnings - so better close it quickly while there is only one warning message.
You cannot change the language selection ("Sprachauswahl") while any of the warning messages ("Frage" means question, but it shows a warning) are still open.
Once all "Frage" warnings are closed, you can select the language for the UI. Currently only the four entries in the top row (de, en, fr, nl) work on my computer. Feel free to try Swedish, Spain, Italian, Japanese, or Russian - but don't be surprised if you get a German UI.
Edit: Update for version 3.8.1(12): Swedish, Spain, and Italian now work on my computer. Japanese does not work under my English Windows XP, but may work on different operating systems, Russian still shows German texts.
The "Gfp-Simulator" error message comes when you had more than one "Frage" warning:

So you shouldn't see it if you closed the "Frage" dialogue quickly.
Here we are, up and running - and everything in English:

German text in the UI indicates new features. "Kohle/Öl" stands for "coal/oil". FS stands for speed step.
The PC version has a small font problem, showing a black rectangle where the Ellipsis glyph ("…") should be:

New features, e.g. new screens created for the PC version are in German:

This screen allows you to switch from Demo mode to a connection to a real CS 2. Here the PC version still couldn't find a physical CS 2 and will stay in Demo mode.
Even without a CS 2 and without any mfx+ loco you can now enjoy the mfx+ Spielewelt and all cab control modes:

Sand is sand, Wasser is water, Kohle is coal.
There are four modes for operation of mfx+ locos:

Our daughter was amused about the "Profesional" mode (a typo I had missed).
Not shown here: you will probably get a few warnings from your firewall as the PC version tries to connect to the network. You should allow that if you have a physical CS 2 and want to connect to it. If you don't have a CS 2, then you can block all those attempts.
Long story short: it's dang easy to get the PC version up and running even if you don't know any German.

Update (08/09/2015):
There is a new file on the download page:
CS2.dmg (120.000,00 kb)
I assume it is the Mac version of the software. It includes a German Readme file with some Mac screenshots.
The download page (German only):
http://maerklin.de/de/pr...ds/software_updates.htmlYou still have to accept the license agreement by clicking "Ich habe die Lizenzvereinbarung gelesen und bin damit einverstanden" to see the download link.
