I have another nice problem with the magnificent system called CRM 2011. It's simple problem, I can't delete a custom entity. While I'm trying to delete entity (it takes 5-7 min then there is an error) CRM is freezed.
SQL profiler and DiagTool didn't give an answer. There were some errors, but they did not relate to the work of CRM. I've checked deletion of relationships, it's impossible too.
System: CRM 2011 Rollup 11.
