Hi,
I have both version 1.3 & 1.5, both don't run correctly after 15 minutes.
Maybe it comes from Windows XP or the firewall (I have Comodo Firewall)
The symptom : after 15 minutes, software screen is totally white (no menu, no windows, no data).
When if press CTRL+ALT+DEL: ANRB.exe don't answer
My config:
Core2Quad 6600 - 2.4GHz
Ram 2 Go
Graphic card : nVidia GeForce 8600GT
