"Checking for Buddy STore products. This may take a while". Nothing else i happening. Have reinstalled it few times, but same thing is happening every time.
The senior staff is looking into the issue. Your work-around is to disable the offending Combat Routines. Gladiator Suite and TuanHA seem to be two culprits, but there may be more. You can forgo reporting to the Support threads. When the senior staff isolate the issue, they will probably communicate directly with the CR authors.
