warning messages

Navigate to the folder where your company files are located. Find the two  files named *.ND and *.TLG and look at their sizes. They should be small, ND about 1 KB and the TLG should be much smaller than your actual data file. These are created fresh every time you log in but grow over time and a refresh may be in order.

Rename each to *.TLG.old and *.ND.old and then reboot and log in again - then view the files to see how they shrank (and possibly cleared up any issues) I just noticed it is time for me to go do some housekeeping of my own in this regard.
