I am bringing in RINEX data from a local CORS station to use as a reference station for post-processing and am receiving this error message:

The data is clean as it is a CORS station and the time span covers the mobile mapping session.
Any ideas?
Thanks in advance,
Matt

Was there thunderstorm activity in the vicinity of the CORS station, by any chance?
MobileMapper Office 3.40A Question - UPDATE
Kent,
No, no storms, just hot, heavy atmosphere. The CORS station was about 6 miles away.
Jeff Austin nailed it, as I had to bring the RINEX version down to 2.10 and things worked after that.
Thanks for the input,
Matt
Did you collect your data real time or post processed. Real time measurements don't have the necessary associated file for post processing. If you have collected in post processed mode, MM Office should be able to directly connect to the CORs using the menu bar at the bottom of the screen. The post processed file automatically triggers MM Office to display these menus and do this.
