I have installed both procedures and SID/STAR files??? Help anyone...!

Hi. I'd use your name but you did not sign your message as required by forum rules.Check what cycle your SID/STAR data is. Normally the errors you are getting are the result of using pre 0401 SID/STAR cycles. You can check the cycle date by opening up any of the SID or STAR files and looking at the header. It lists what cycle it is. Current cycle is 0406. 0407 starts on 8 July.RegardsTerry
