Windows 7: 2 Problems

Hi guys here are my 2 problems:
1st: When I play GunZ I see the right and the left of my screen black....How to fix this?
2nd: I must open some files .dds but can't because I have a stupid error: Impossible to complete the request because isn't the right type of document. How to fix this? (I've already tryed to reinstall dds plugin 10 times and 4 with different versions).

Help me pls :*::*::(::(:

When I had Windows Vista I didn't have this problem...


(Don't tell me to trash this computer)

1st: post screenshots so we can see what you exactly talk about
2nd: you need photoshop and just get the dds plugin for photoshop

for the first problem, it could be some resolution errors... try playing at different resolutions...

To fix ur first problem is very simple.
Open config.xml and find this at the top...

Code:

Change 1024x768 to your screen resolution.
