If you still have PTS installed, download this (ftp://l2clientdownload.lineage2.com/Chronicle04/L2_C4_Live_Conversion.zip) to convert PTS to the regular game client.
Check you firewall, either disable the firewall and try to log in or switch to windowed mode before you try to log in so the firewal message will pop up.
I did think of that and tried it, no problem w/ firewall. For some reason I think I may have changed my "Host Ip" if anyone knows theres id like to compare it to what mine is. thanks.
