Just installed Morrowind again and I got a problem with the Bloodmoon expansion.
When it is loading the game there pops up like 6-8 warnings all about the weather.
Something about WEAT ID and about the weather in some place not matching up to 100%...

If it is needed I guess I could write the errors down here but hopefully (since I cant write the stuff down while it is in place) that wont be needed...

So, anyone knows what the problem is?
I got a Vista if that matters.

Be sure to Install Tribunal before Bloodmoon.
You'll also want to check the http://www.gamesas.com/index.php?/topic/781497-vistawindows-7-problems/ to avoid other problems with installing/playing on Vista.

Aha! The "install Tribunal first" thing may be the problem. I will uninstall Bloodmoon and reinstall it afterwards, hopefully that will work.
I will also take a look at that thread, thank you!
