This has been resolved in version 2.005.1.1
Issue: Deadlock Detected
The error occurs when mulitple SubRES files are imported together:
Workaround: Go to Tools -> User Optons -> Syncing Options -> Set Threads Count to 1 and press update button.
After sync is completed, reset the Threads count to -1 or previous value.
Do this only when you want to sync multiple SubRES files together
