UO Second Age

i am getting this error message when i try to start Razor:

System.InvalidOperationException: This Razor installation is corrupted.
at Assistant.Engine.Main(String[] Args)

anybody have any ideas on where i go from here? I have tried removing it and re-downloading Razor_latest from the razor website. Ii have also tried to run as admin and of course i remembered to restart the laptop.

Thanks in advance for any help

i downloaded an older version of Razor and it started first time. Problem solved

Arghh.

i could not get past the 'verifiying account' screen so i followed a sticky and re-installed the latest version of Razor, now i have the same error message.

fingers crossed for some help again.
