Please go to the settings dialog, advanced page.
Find the entry "DebugOutputString" and set the value to "true".
Then kill the TSVNCache.exe process.

Now, get dbgview from Microsoft:
http://technet.microsoft.com/en-us/sysinternals/bb896647.aspx
start it and record the outputs from TSVNCache.

I need the log file of those outputs. Maybe I can see more there.

I'll have a closer look.
