The problem is that every time they do an update it puts all security futures to default. What is the default? 1 FTP session per account. No host is pleased with our type of accounts, live update every 10 sec. plus all other uploads (web cam/s, 5 minute uploads for various files, video, forecasts, lightning etc..) they put a lot of strain on their servers and they don't like it. Had the same problem with my host, I was lucky and managed to have 4 FTP sessions open, but they kicked out a friend of mine. So just ask your host nicely to open more FTP sessions for your account. If your problem is not solved try to cut down on transfers, sometimes we over do it by uploading stuff that is not all that important to anyone.
