I have been playing Morrowind for weeks now (again) and have it modded and was running just fine, even last night, and tried to run it again today when I got home from work, and I get "0 Continue running executable?" What exactly does '0' mean? Its while initializing data. Like I said, it was running just fine just last night. Here is my Warnings.txt contents:

Not able to find Foot part in BC_shoes_common_2.
Not able to find Foot part in BC_shoes_common_03.
Not able to find Foot part in BC_shoes_common_1.
Not able to find Foot part in BC_shoes_common_03.
Not able to find Foot part in BC_shoes_common_5.
Not able to find Foot part in BC_shoes_common_1.
Not able to find Foot part in BC_shoes_common_1.
Not able to find Foot part in BC_shoes_common_2.
Not able to find Foot part in BC_shoes_common_4.

Just all of a sudden. I didn't try continuing, thought I better find out about this first.
I always save my game in a new file, everytime, except the autosaves, but the last save of the session is always a new save file as well.
Thank you.

Something I just noticed is, when I load the Morrowind Launcher and go into data files, I go down to the save files and click on each one in order of save date/time to look at the info for them. Even though I go in order, the game day changes randomly, for instance [save 1] will be day 1, [save 2] might be day 1, [save 3] might be day 14, [save 4] might be day 13, and so on. Ya think I have corrupted saves? I have been looking all night and cannot find any reference on the net to error "0".

Are you running Better Clothes? Be sure you have version 1.1.

That said, open your Morrowind.ini file, and add this line to the General section:

AllowYesToAll=1

Then save it, and exit. You shouldn't get any more questions like that unless you encounter fatal errors. Try reloading, and see if the game runs.
