That's a pretty random error message. It doesn't even tell you what went wrong. I sent you the whole kit didn't I? The safest and surest thing at this point is probably to port your stuff over into the kit I sent you. And just in case, only port a few custom scripts at a time (starting with whatever menu system you're using, of course), and see if any of them break it. That way we can narrow down the cause.
i mean go through and find any script changes you ever made that you want to keep, paste them in a text file or something, and replace your scripts.rxdata file with the one in the kit I sent you. it seems like a compatibility issue between scripts, but it's hard to target as is. just keep a copy of the scripts.rxdata file you're currently using just in case.
