I believe its version 11 from 2003. When I try to program it, error messages show like voltage error and it says something like cant make contact with radio, except everything I believe is hooked up ok. On the portabel RIB I have it has 4 lights the yellow flash works, the rad PC light woirks and the green power light works, but the rad radio light doesnt light---so I dont know what I am doing wrong. As far as speed of computer I have an up to date one with windows XP and a older slower 486 with windows 95. Any help would be appreciated. Thanks Brad
