I meant Connection cache has to do with out of date connection hosts so to speak, perhaps the ones you have are old. It sounded like you'd been using the program for some years so perhaps the connection cache had become outdated. Same thing happens to most gnutella programs.
Else-wise you can go to the shareaza forums & seek help there.
