Why Soulseek abort downloads and uploads

Hi everybody,

I have a lot of issues with my soulseek client in mac. The client connects quit well but all the files, upload and download files, starts fine but suddenly they are all aborted. I have the ports open and all is set properly. I use Soulseek for years and I've never have problems with the client but I don't know if it's because of the new clients but it's no working. I've tried to change settings in my router but it doesn't work, too.

All the problems starts when I moved to UK from Spain. In Spain the client worked really really good. I was wondering if maybe my net provider, Virgin, is blocking Soulseek in some way. Everybody knows something about it? It would be strange because Utorrent works really nice.

I need help! Thank you!
