The key was working and verifing the date, but when we went in to system preferences it gave us run the master work station. I became stuck in a loop that I couldnt go into POS inventory because I needed to run system preferences and system preferences wouldnt work because of the master workstation needed to be run and the key was being seen.

SOLUTION: Remove all the RTI keys out of the registery, then do a find in the registery for rprows and delete that and the rpronet statements. then go to autoexec.nt and delete any rpro statements, restart the computer and re-install the workstation install.

Also check for conflicting RPROstatements it was the issue wit a client I worked with
