File not shared error after a while

I can download and browse files from some users, but after 2-3 weeks I get : There is an error "remote: file not shared". When I try browse files it says "no files shared". But I know they shared, there is a shared-files-info in the userlist.

Last time I reinstall soulseek and problem solved. But now I cant solve this with reinstalling. I think this is some kind of bug. And I can't understand the source of the problem.

Please help me.

(my port is open)

Well, recent SoulseekQt builds have a way to "unshare files from user". Once the user you're downloading from decides to do this, this is what you will see.
AFAIK (don't hold me to it though) the shared files info in the userlist does not depend on that. Yet this does not necessarily mean that you can access this number of files shown, too. Consider that the "unshare files" setting is a per-user setting.
