Worms 2 on Windows 7 -- PLEASE Help!

[zim del in]

Earlier tonight I installed and activated Worms 2 via trymedia. It was working perfectly fine except for some minor coloration issues. I closed out of it for a bit, and then when I re-opened it, the options and such loaded fine. But then when I tried to enter into an actual game, a box popped up titled "Frontend" which reads "Access to an unnamed file was denied."

I have no idea how to fix this. Any advice at all? Will I have to uninstall and re-install, and if so, then what's the process for doing that and re-activating? Or is there just a way to fix this without having to go through that?

I absolutely love this game and haven't played in years.. please help! Thanks in advance

Where did you install Worms2? If you installed it into Program Files, don't do so.
As for the color issues, use DirectDrawFix (http://www.xomicron.com/download/directdrawfix/) by xOmicron. Choose Worms2.exe there and apply, and you won't have such issue anymore:)

I installed it into Program Files (x86) -- it's working now, I just had to select to run it as the administrator. And that program fixed the coloration issues, so thanks so much for that
