Problem with MV Group taking over uploads?

Hi. I'm new to the forum and I don't know much about this torrent thing, but have been using Limewire for about a year. I am running Limewire 4.16.6 Pro, have 10 open slots for uploads, 43 high quality movie files available to share in the Limewire folder, 10 upload slots, 100% bandwidth permitted, and have usually been uploading at about 130 KB/s collective average, and I never turn my computer off, except to reboot occasionally when things slow down. That is, I was until two days ago. That was when I discovered that the one file I couldn't find to complete my BBC series was available at a link at mvgroup.org website. I selected the link there and the file immediately started downloading with Limewire. I also found some other very good documentaries and downloaded those also from them. Ever since that time no one other than their group has been able to download anything from me. It is always the same: exactly five uploads (out of the ten slots available) and just the titles I have downloaded from them, seeding. I see searches coming in for the movies I have, but never any of the other movies is uploaded. This is a complete about face from before I downloaded anything from MV Group. All the available slots had always been used. It appears that this group has commandeered the uploads, shutting everyone else out. Strange thing is that they don't even use all the slots available, but no one else can use them either. Anyone have an answer for this?

Strange things are happening. I just checked my Limewire monitor after posting this and now I am uploading again, 9 of the 10 slots, and at 124-129 KB/s. Odd that I am suddenly uploading to Limewire and BearShare users again after not uploading a thing to anyone other than MVGroup for two days.
