ARC8600 for RadioMax?

The v5.20 demo of RadioMax currently offered on their webSite seems to have 
trouble installing and running under Windows 2000 Professional. Although 
RadioMax tech support tells me "I have sold hundreds of copies, running on 
all the Windows platforms including NT/XP/2000/95/98/SE/3.1 etc without 
problems", my experience indicates otherwise. Another problem is that the 
online manual provided differs from the Demo software in several areas. So, 
I'm wondering if the Full Install package might somehow be different from 
the Demo and work as advertised...

I'm willing to experiment abit to give RadioMax a fair try but given what 
I've seen to date, both with the software and tech support, I'm reluctant 
to invest in the developers while I debug their program. 

Anyone want to trade current RadioMax for BuTel ARC8600 (software for AOR 
8600B)?

Thanx,
Bob
