I'm a long time Bear Share user but, a first time poster. So I want to hi because the rules say so. lol

I had Bear Share 5.2.5 for a very long time. Loved it. About 4 months ago I re-formatted the computer, re-installed everything, re-installed Bear Share and now it won't connect. So I installed the new Bear Share 8 to see if it would work and it did but i don't like it as well and would really like to go back to 5.2.5. How can I get it back up and running?
