[NA-User] Error 75

[Hoeft, Roger V]

Folks,
 
Anybody have an NA crash with error number 75?  I was trying to configure the computer for NAQP this weekend and every time I got to the keyer settings page (weight, Curtis A/B, etc) NA would kick me out with Error 75 and an address location.  This happened with NA 10.59 and earlier versions.
 
Anybody know what gives and how to fix the error?
 
Thanks & 73,
 
Roger ...
