Game won't unpause

[Weiss Pinguin]

Hey, first thread in the SH4 room...

Anyways, I got SH4 Gold edition for Christmas, and after getting home last night finally loaded it up onto our computer (My computer is down and out at the moment, and wouldn't be able to run SH4 anyways), got it working and quickly opened up the Navigation lesson to make sure all was working, then closed the game for the night and restarted the computer.

This morning, after a hickup regarding some game settings that apparently got reset ('No, I wanted **** x ***, not 1024 x 768', and 'No, I did not want windowed settings, silly computer'), I loaded up another lesson make sure all was still working. And it was, except for my pause and TC buttons.
I guess the problem isn't really that the game won't unpause, it's just that it keeps pausing. No matter how many times I hit Backspace the game keeps on hitting it right back, and the keyboard shortcuts for TC don't work at all. When I manually click on the TC + button, the game pauses again.

I did a quick search, but I couldn't find any other posts on this 'feature', and I'm pretty fed up with it by now.

As I said, I'm running SH4 gold edition on Vista. FWIW, I installed the game on an external drive that I normally use with my own computer, which runs XP. I dunno if that could cause any problems, but I noticed that after installing the game on the external drive no shortcuts for the game showed up in the Start menu.

Anyways, thanks for reading all this, hopefully it wasn't too confusing...
