Hi there, the title pretty much explains it, but to describe the issue further:

I used to have the Morrowind lockpicking mod and recently disabled it, but now I can't seem to get the lockpicking game to show up at all. I use FCOM, but I don't know if that would affect it at all. Basically, when there is a locked item and I try to use it, nothing happens at all; there is no text at the screen to explain why or anything.

If anyone could help shed some light on this situation I'd greatly appreciate it!

From the readme

AH! Thanks! I'll try that out. I didn't think I would because I used an OMOD of it... guess it stuck somehow!

Did you just uncheck the esp or actually disable the OMOD? Disabling the OMOD should remove everything.
