win2000 Pro running Lime 2.7.13 and then 2.8.0
Had issue with connecting and freezing.

What seemed to work:
- Removed all installations of Limewire
- Removed my old version of JRE (had been j2re1.4.0_01)
- Installed new Limewire beta 2.8.0
- Installed new JRE (j2re1.4.0_03)

Launches fine, connects OK, download and resume seem to work. Though running as Ultrapeer seems a bit squirrelly - lots of connection activity and not much in the way of search success. Prompted me to disable Ultrapeer.

Hope this helps y'all!
