Hey, gang, need help on this one. Been using VarAC for a while on another computer. No problems. Now setting it up on a faster Dell for the shack. Upon opening I am getting this error. I have been tangling with this for several hours to no avail. Any help appreciated. VarAC Ver 6.3.3 VARA installed .NET error message: See the end of this message for details on invoking just-in-time (JIT) debugging instead of this dialog box. ************** Exception Text
