I have been digging further into my problem with timeouts. When I start with a fresh and rebooted computer there is a good chance that I can make 20-100 audio checks with music IP, but then I get a timeout (300 seconds according to the log, which seems right according to the timestamps) and suddenly the rest of my scheduled lookups just get finished in seconds, with the same error message for every file (that is, without even trying to get anyting from MusicIP). When this has happened there is nothing I can do to restart MusicIP lookups again, except reboot the computer! Any ideas? Is it genpuid.exe that is messing things up here?
I have shut down my firewall, checked on two different computers (XP and Vista) and also bypassed my router just to exclude all possible error-sources in the network.
