Can't Connect--tried everything

[slugirl19]

I am at a loss of what to do. Firstly, this isn't my first time using LW also I have successfully connected to this wireless network before. I was successfully connected about a week ago. For some reason when I started up LW it would not fully connect. There is one green bar showing the rest are red--meaning no connection. I don't know what it could be because i HAVE connected here before. I tried restarting the program, also I completely un-installed and re-installed the program. I am like really angry right now because I just want to download music and I have no clue what the hell is going on. Also my entire library is off of LM now since the uninstallment...just great
