It does not seem to start at all on 10.10.1(French) The previous version started but then crashed on output. I do not have much more details as this was not on my machine. Apparently running the windows version on Mac is also a problem on 10.0.1
On the first open file StarTools crashed. I can send you the crash log if you would like. (I am not able to attach .log or .txt files as attachments here and the output seems too long to paste into the message body).
Subsequent file opens worked.
Digital Development Home In did not crash as it did in 298. So something you did worked.
When I turned off tracking, noise reduction didn't come up. I only tried this once so it could have been operator error.
