"Script error on opcode 376"

[LordDrakull]

I don't know what this is but it is really really effecting my game. Why does it show this? And is there any way to fix this annoying thing?

You'd need to report the rest of the script error text for us to know what is going on.
Are you playing clean Native, or have you tweaked it or are you playing a mod?
