Runtime Error

I'm trying to set up an unattended monitor but can't keep the WSPR software running for any extended period. I turn things on and walk away with everything FB. Within a day it drops out and I get the following:

"Microsoft Visual C++ Runtime Library
"Runtime Error: Program: C:\WSPR\wspr.exe
"This application has requested the Runtime to terminate it in an unusual way.
"Please contact the application's support team for more information."

Running WSPR 2.2 r3617 on Windows 10.

Yeccch!
