Don't panic, yet! hehe

See the link near top of page (above your post) about System Details, click on it & post back the details about your system set up, and we will see if we can find anything which stands out that might be contributing to your connection problematic issue.

Oh and also, go to your LW menu bar, Tools menu, choose Advanced Tools & (a) tell us if you see any connections listed that are stationary & not dropping away. If connected normally you would see 5 connections for LW Pro (only 3 for Basic.) (b) Also, what does the message at far left of that window say about firewall?
