Soundtaxi R & R Error

Well I used the Soundtaxi trial and of course everything worked well. After I bought the program it was all down hill from there. It will convert a few songs and then I get a must install R&Rinstall.exe message. I did that and rebooted, then I get an error saying soundtaxi is not properly installed.
Anyone have this same problem or a solution? I am using Vista Premium if that helps.
If Soundtaxi is too problematic, is there a program that is better. I would prefer one that can do folder monitoring and automatic conversion like soundtaxi does.

Hi,

had the same problems when I began with soundtaxi. Make sure that you have full rights as an administrator when opening soundtaxi. Change the rights to soundtaxi.exe, the soundtaxi directory and the directory soundtaxi is writing to. Even if you thought so this is not the standard setting in vista!! Eventually disable the user account control (uac). You might do this for the administrator accounts only if you want to stay with this sucking functionality under vista.
