Power failure, a reset upload queue, and sharing woes

I've recently experienced a electrical power failure which resulted in a reset of my SoulseekQT client. Before the reset, my upload queue showed about 1500 uploads to what looked like 100 or so users. But now I am receiving messages from angry users saying my files are not shared, even though I have set my folders to the exact same share configuration as before. Users are still able to manually browse and download files from me...it just seems as though their previously queued uploads are not being honored. Is there anything I can do to get their files started again? And more importantly, is there anything I can do to avoid this problem in the future?
