3.6 to 4.01 Upgrade Issue (3.6 still starting)

[levi]

I recently installed 4.01 over my 3.6 installation. I edited the SUBSONIC_ARGS variable to set the port as it was in 3.6. But when I navigate to my Subsonic log in page and log in, I still get 3.6.

I have checked the subsonic.log file and get:

* an SQLException that the database is in use by another process
* a WARN NetworkService - No UPnP router found but port forwarding was completed
* the INFO VersionService resolves versions 4.1, 4.0.beta2, and 3.6

Questions I have:
Does any of this point to the isssue?
Where did 4.0.beta2 come from?
If a UpnP router was not found, why was port forwarding successful?
Why is 3.6 still starting if I have installed 4.01, wasn't it replaced during the 4.01 install? (if not, there needs to be some upgrade instructions written)

Any hep would be appreciated.
