We don't know much about "Bearsharev6" other than that it is actually a counterfeit based on
what used to be iMesh. The company that does this have avoided having forums because they
don't want people to find out about it. I don't know where you can go for help other than by
sending an email to that company.
If you want to try out the real BearShare, try reading this thread:
