General error in Spectral Tools.

ePMP 3000, just updated to 4.4

Tried to use the Spectrum analyzer for the first time since updating to 4.4, and I get "General error in Spectral Tools." in the Notifications.  I tried disabling and re-enabling it and got the same thing.  Any suggestions?

rebooting seems to have fixed it

i have received the same error. I suspected that maybe it was due to having the SA already open in another browser session, but i couldn't really duplicate or eliminate that theory.
