Sorry to hear that you're having problems - lots of people don't like the new LW 5
You can revert back to LW 4.18.8... go to LW's download page, click on the Get Basic button & you'll see a box with a link to click for old installers.
Have you been through the fixes in this thread?
If LW Will Not Connect
Start off by deleting your gnutella.net file if you're still using LW 5, or you may need to replace the file if you've gone back to LW 4.
If nothing in that thread helps, please post back with your system details.
If you paid $49.95 for LW then it sounds like you were scammed. Did you pay for Pro (basic LW is free)?
The official LW site offers Pro ($21.95, 6 months of email support & free updates), Extended Pro ($34.95, 12 months of email support & free updates) & sometimes a one-off download for $13.95 (no updates & no support) or 6 months.
The only official site for download (shows on your CC statement as payment to LimeWireLLC) is
Lime Wire » Download LimeWire
Who did you pay for LW, how much did you pay, when did you buy LW & did you get basic LW or Pro? The threads below have more info about what to do if you've been scammed
