I too am having the same problem. I have tried the suggestions listed below with no effect. I checked the last known successful connection to Limewire; it was May 8. There were 2 "update" installs from Microsoft since that date - for me. I using the "restore" option from safe mode but could only go back to June 9th. I did try several dates just on principle, to no avail. In that time Java also updated. I tried the Java fix you suggested, and still nothing. I uninstalled limewire and Java. I removed everything Limewire form the pc and the registry and tried to reinstall both including a rolled back version of Java v. 1.4.2-14. So far nothing has worked. No real new information here, but I thought it might save some time and frustration for someone else.
