I'm running Windows XP on a laptop, have installed Lego Mindstorms 2.0 and Bricx Command Centre , connected the USB tower, but both programs complain about not being able to see the RCX. I've tried everything. Now, I heard something about a patch being available that might solve this. Any one know how to get this? (not the patch RIS20XPPatch3.zip preventing the automatic startup). Is there another way to test the communication?
