Error 1073807194 occurred at Property Node in Visa Configure Serial Port (Instr).vi

Hi,

Yesterday I began collecting data from 4 different instruments while running a test. Data was being collected once every 10 seconds and graphed and written to an excel sheet.. Everything worked fine for over 12 hours. At 1:00 AM Labview gave me this error and stopped my code. After closing labview I'm not having trouble even starting a VI or using MAX, the programs stop responding and I have to force a close. I'm not sure what happened. Would really appreciate and insight. All my read serial ports use a close visa after them.

Also of note, my VISA channels seem to be gone. I can't see them in the drop down list in labview, and I can see my cRIO in MAX but it says no visa resources found.
