I did not investigate what hidden processes was Soulseek 2013.07.01 running since after a dozen crashes I gave up, uninstalled it and reverted to good old version Soulseek 1.57 NS 13e. After a couple of hours I still got the same message. Please try resubmitting the form in a couple of minutes.'. Per site policy, we are unable to accept new submissions until that problem is resolved. I tried to report the problems I had encountered in Soulseek forum but this was not possible- my old account had been deleted and I could not create a new one because I always got this message: 'The spam filter installed on this site is currently unavailable. Any time I tried to perform a search it always froze and the only way to close it was via the task manager. More, old Soulseek NS could index 300 GB for less than a minute, while this one did not manage to index anything for about an hour, I always got the message that 'It seems that you are not sharing anything'. The interface is messy and confusing, it does not even have a context menu when it is minimized to tray for example, so it cannot be shut down via right click on its icon and choose 'Exit'.
Since old Soulseek NS does not support Unicode I decided to upgrade to the QT version (Soulseek 2013.07.01), which turned out to be a total failure.
Soulseek NS was excellent but these new Soulseek QT builds are terrible.
