Hey Julius
As soon as Sven wrote his reply I it made sense (pity a few off us all asked the question at the beginning regarding status of structural). But yes, actual screen shots of the configuration or what the error are showing would make root cause analysis easier. It's become another guess the issue with vague details game.
Thanks for detailing my comments further as well
Btw, I thought SUPC and PFUD improvements on cleanups will now resolve the UST* and USR* corruptions. Good to know about SUIM_OLD though as I've discounted most *_OLD transactions as deprecated functionality 
Cheers
