I had this problem too, I found that when my computer (XP Professional) went on standby mode, it kinda logged off from the desktop on which Relax was running and cut the connection causing the timeout. To fix this problem, I right-clicked on the desktop, chose Properties, Screen Saver, Power... Then I changed some of the settings (ie System Standby) because they were setup to turn on early (20 min of inaction)... I hope this helps! Now, if someone can tell me why XBMP Network stops when I hit the pause button...
BTW: I have a 1.0 XBOX with a Xecutor 2 Lite -X2 4973-XBMP 2.4 -Relax .75
