HELP - There was an error during startup. Please see Log for more details. [CLOSED]

Hello!

I seem to have been forgotten, so I post my problem again.

I'd just installed the "70s 80s & 90s" stuff pack when the launcher gave me this message as I tried to play the game:

"There was an error during startup. Please see Log for more details"

The regedit-video suggested for this error has saved me once before,
but the example only has one expansion and I've got every damn expansion installed, so what can I delete?! O_o
I mean, aren't all of them supposed to be there, in regedit, if I've got them all installed...?

Thanks for your help! =)

Sorry if you were forgotten, it sometimes gets pretty busy in here...
This fix is for when you uninstall some of the expansions.
What are the expansions you have? In your Registry Table, at that place, what games are shown?

That's the original topic. We hit on a lot of things when trying to solve it there. So I'm going to close this topic, and make a post in there so that one gets bumped back up.
