Grabcad Print ERROR: FDM Build Service has terminated unexpectedly

When starting GrabCad, I get the message "FDM Build Service has terminated unexpectedly." Further, I cannot start any prints, receiving the message "Cannot start FDM Build Service"

Everything was working fine several weeks ago, not sure what changed.

WOW, ok, found the root cause. I have an .Xdefaults in my user's home directory. This file had the following two lines:

*background: rgb:33/33/33
*foreground: rgb:ff/ff/ff

Removing them fixed the issue. *sigh*

set "HOME="
set "HOMEDRIVE="
set "HOMEPATH="
set "USERPROFILE="
