Hello, thanks for read this my post. Some days ago my modem/router is broken and i changed it with a Sitecom 300N. After changed it i have big problems in SL: I lost the groups, the information in about land, i crash in teleport, and music and voice don't work. I can only make a log in and use im. I tried with Windows XP, Vista and Win7 and also with Linux. and I tried with SL2 viewer and also with Phoenix .. The issues are the same! I have disabled the firewall in modem and i have no firewall in the operating system. Why I have these problems? can everyone help me, please? thank you soooo much :-)
