I'm running 4.9.37 Pro. I have tried some of the never versions, but it seems like my laptop likes this version.

2 MBit down 0.5 MBit Up (Limewire T1. Unlimited Down. 50 Up. 5 slots)
Toshiba Qosmio F10-136
Windows XP MCE 2005
1.7 Ghz Pentium M 735
512 MB DDR ram
6+ GB free harddiskspace out of 40 on the one Limewire is installed on. Just deleted incomplete folder. (maybe 500 MB in it now)
SMC BRA 7204 Router (Can't get it to use portforwarding for some strange reason)
NAT Firewalled (using UPnP) Brickwall in front of globe, but this has never happened before. The test says true or OK (can't remember)
JAVA J2SE Runtime Enviroment 1.5 update 6
No newly installed programs
Have never needed to delete preference folder in about 10 months (could that be it ??)
Usually I can download fine exept for limewire message sometimes popping up saying that I have no internet connection (but I'm still both downloading and uploading and connection goes straight to turbo again ??)

I have never noticed Limewire doing this before last night. I tried connecting again. It only stayed connected for a few minutes and very few searchresults came up when I tried searching (the whole time I was still downloading at between 80 and 140 KB/s)

Seems very strange to me
