I think this is only happening with Bloodmoon, because I did an uninstall, reinstall, and it stopped happening, but as soon as I reinstalled Bloodmoon, it happened again.

I try to open Morrowind, and I get a message that says "Error: Failed to load snowflake: Meshes\BM_Snow_01.nif"

Not sure how to fix it. As far as mods, I do have a lot of graphics and texture mods installed, BUT, I have gotten this message when I had not a single mod installed either. So I do not believe it to be mod related.

This is a problem caused by Vista and Windows 7.
The easiest way yo correct it is to just http://www.gamesas.com/index.php?/topic/781497-vistawindows-7-problems/page__view__findpost__p__11352753. This will also avoid some problems that can occur with mods.

Edit: ninja'd.

Thank you for the replies! And sorry for posting it in general, I realized after I posted there was a tech forum for this

I was able to fix the snowflake issue, but now unfortunately, I'm having loads of mod issues. Time to head over to the mods forums, methinks, and see if anyone else has the same issues.
