The function was not activated. I removed the playlist import option when I add tracks, so I think they will not come back . I have ereased all the imported playlists. Shutted down, and restarted, and ho and behold, it opened almost instantaneously (hard word, that, for a non english native, sorry if it's wrong) I think we can call it a closed case. Thank you for your time and the answers :)

I have gold so it's not impossible. I could have activated it when I scanned for my files. I just don't remember if it's the case or not. I would not have done it on purpose though as I have never used that feature on my other computer.

It's not activated by default, and you need Gold to be able to activate it.

I have no way of checking if it's enabled or not right now, as it's trying to start. I think it's not enabled, but I can not garantee it. I did not activate that function, but maybe it's activated by default.

I'll try your solution as soon as it opens and get back to you.

Do you have File Monitoring enabled? Disable it or deselect the Playlist File Types under File > Add/Rescan Files.

I have news. The loop seems not a loop because "after some time" (I left it in my taskmanager) MM opened. "After Some time" = at least two hours, but I don't have a precise timing. To think of it, it might be the imported playlists (the one imported when scanning the hard drive to add music, the .m3u files and so on often found with mp3's) that might cause the trouble. At least it's what I understand from seeing the same request over and over and after a very long time, MM finally opens. Is there a way to not scan thoses files ? I don't use thoses playlists...

I can give you a full debug file when it finally opens (I closed it by mistake). As for the database, it's more than 3 gigs big, I don't know how to send it your way.

Hi.

I recently bought a new computer and installed the latest version of mediamonkey on it. I proceded to move my collection to the new database, leaving all the music on the other computer (I access is through the network). All was working fine, but after a day, I can not open mediamonkey anymore. I tried removing the usual dll for iphone and ipad (quicktime corruption work around) but still it was not working.

I installed the debug version of mediamonkey, but could not produce a log since it's not starting so I took the debugviewer and looked at what was happenning. Here it is:

As you can see, it seems trapped in a loop. What can I do to solve this ?

edit: If i remove the database, mediamonkey starts fine, but I don't want to do that because I have a huge database (800.000+ songs) and it takes forever to put it back inside mm, and it's the second time I'm doing it.
