Elan DRC e pumping down

Hi All,I've been using these forums for years to troubleshoot my Elan DRCe but I am having an issue that I have not seen on here or anywhere else, for that matter so I thought I would throw this out to see if anyone has had a similar problem.I had just finished running some particularly nasty samples so I brought the system down and cleaned all the sample intro parts (neb, spray chamber, torch, injector, cones) and I also cleaned the lens and changed the pump oil. I brought the system back up and restarted the vacuum (pump). The pump came on and the instrument began to pump down. In fact it pumped down to ~5e-007, which is plenty of vacuum to ignite the torch. The issue is this: on the software, the "Front Panel" display window where I start the ignition sequence when everything is green, the torch chamber and smaller, backing pump are still yellow and the "ready" light on the instrument itself is still flashing. Everything looks good as far as being able to start the ignition sequence except I can't because of the yellow torch box and pump.It is almost like the computer software isn't communicating correctly with the instrument. Has anyone seen anything like this or have any ideas on this issue?Thanks!Shawn
