Here is what LEGO should be doing right now:
1) Putting something up on their website that acknowledges there is a
problem, that they are working on it, and a planned target date for
resolution.
2) They should offer people the option to exchange the USB IR tower for
the serial one until a resolution is found.
In the meantime, those of you having problems could try disabling
Hyperthreading in the BIOS, which should effectively disable it in
Windows XP.

| (...) The problem is that they never promised to support XP. The only thing listed is 98/ME. In fact, they explicitly say 2K and NT are _not_ supported. (...) Everywhere this is mentioned, someone says you have to reinstall windows after doing (...) (21 years ago, 6-Jan-04, to lugnet.robotics)
