I’ve been happily playing kudos for the last few days as you do, and now when i want to play it, it says:
C:\Program Files\Kudos\Kudos.exe is not a valid Win32 application.
Could you please tell me what the hell i’m supposed to do to play my game happily once again.
Thank you.

The file has become corrupted somehow. Thats very bizzare, but you should be able to uninstall and reinstall it and have it working fine.
Best to backup your save games (in the mydocuments/kudos directory) just in case, but generally they should stay there ok.

In fact, backup your entire hard drive, regularly–each week, if possible. You’ll never regret it.

Back up the entire hard drive? ha, how the hell?
Anyway, thank you, i uninstalled it, somehow, thanks very much.

The best and easiest way is to buy an external drive. They’re many around, they’re pretty cheap these days, and can hold a great deal. Then get some software to automate it, and backup your hard drive at night when no one’s around. You can recover anything from a file to a folder to an entire drive.

You can also backup to read/write CDs, but that has to be done manually.

I think Microsoft actually has a tool that can automate this. I use it on my computer and it’s free if I recall.
