installation corrupts

[Sal C]

Hi, First post here. I had been doing well with LW. Then I started having problems connecting during my music file searchs. Only 1 bar was showing. Decided to uninstall LW and re-install. After reading some stickys on this forum, I realized that I did not remove LW correctly..So, I installed cclean, and just got done with that. Before running cclean, I would get the msg "this installation is corrupted. Please download and install LW again." I would do this, but to no avail.
Now, should I try installing LW again. Windows 2000XP Firefox, LAN connection
