Reporting back: I fixed it.

Reason is still not clear. But somehow I fixed it.

From all the mess I've gone through, I would assume the reason is NOT graphics related, nor TWoS. It seems it's the registry had some issues.

Clean the registry completely. Always install with CD/DVD. NEVER just move the game elsewhere and then copy it back.

Anyway, thanks for the help to everyone! Cheers!

Don't you have any idea what did you do wrong?:doh:

I think it was the registry. Needed to create a new user account so that I start off with a clean registry...

I don't think I'm following you. What's caused your UI problems in the first place and what would be your suggestions for me if I say that I'm experiencing the same problem ?

If we don't draw some conclusion from this thread than everybody's time here is nothing but wasted...

Should I join similar discussions at all next time someone asks similar question?

Veco,
OP's problem was moving program folders on his computer, namely the SH5 folder containing all or part of game files, a thing that should never be done.
Your mod installer got confused because of that and has installed the files at the bad place (including the UI files). This has caused OP's program malfunction.

So TWoS is not the cause of this malfunction.

Hello guys, I have the same issue. Do we still not have any clear solution to fix this ? Thx
Cause when removing the interface everything is ol and the black part disapear.
