The atma command did not seem to work. The error message “cannot initialize parameters for RCU1” appeared. I was also not able to access my previous spectra. When I try to open one to take a new spectrum, the error message “Data set doesn’t exist, or is not accessible, or is corrupt.” appears. Also none of my files appear under the browser tree, so I had to use the protonstd file and encountered the atma error.
Did not generate a new profile on login.
Automatic tune and match failed for my sample in CD2Cl2. No problems with the sample on DRX499.

Temperature was at 283K even though it was set to 298K. The probe heater was OFF.
Heater was turned on, temperature returned to 298K per normal equilibrium.
