Yep, tried it. Snowflake error still always happens until I reinstall or copy files off Bloodmoon disc after installing overhaul - even after a complete reinstall off the discs run as administrator.
And after I copy Bloodmoon over or reinstall(reinstalling caused additional errors but after copying it's almost perfect), poor Elone is stuck in a giant yellow jello block thing,
Can you copy here your Warnings.txt file (Morrowind folder) when you have the yellow block on Elone?
EDIT: Regarding the "snowflake error": make sure that your [Archives] section of the Morrowind.ini file looks like:
[Archives]
Archive 0=Tribunal.bsa
Archive 1=Bloodmoon.bsa
Archive 2=Flora Glow.bsa
If not, replace it with this.
