SUM (SkyProc) Lootification help please

[nutrigrain]

I've tried running the Lootification proccer by itself, and generated a blocklist for most errors, but then got a new error:

 

There was an exception thrown during program execution: 'java.lang.RuntimeException: -1'

 

I then tried running it Lootification through Sum-it runs, but still generates the same error, at least using SUM, it goes onto the next proccer instead of just closing.

Does anyone know what might cause this?  I can't find anything useful here, on the Nexus, Google.   I've used the blocklist to clear out the normal errors, and can't see anything unusual in the logs, but I'm not an expert.  Here is the Debug overview:

The LLI.esp file isn't liked by Wrye Bash when I run it to process the bashed patch, could it be something to do with that?  I have been deactivating it to process any bashed patch, as it does that anyway.

Bit stumped.

Cheers.
