Here is the problem. I recently bought an HP Pavillion dv6000t. I installed the free version of LimeWire and everything worked fine. I used it for a few days, then I decided to format the hard drive to rid myself of all the crapware that came pre-installed. I installed a clean version of Windows Vista Home Premium and purchased LimeWire Pro. After a successful install, I went to run Limewire. Upon starting my internet connection was lost. This only lasted a few moments and then I was reconnected. However, I never get connected to the network and am stuck with the lower left hand corner only saying ‘starting connection.’ I have changed the compatibility back to XP with no success. I have taken it off of the exception list for Windows Firewall and re-added it with no change. Any ideas? Thanks
