I just finished a flight from KCLE to KLGA, using the same VORs and intersections which David Paul wanted someone to test.  Used Plan-G3 to create the plan, saved it, then exported it as an fsx .pln file.  Did not encounter any problems or fatal error issues.  Used the Captain Sim 727-100 with Eastern Airlines livery.  Also using Active Sky Next and FSX Fiber Accelerator.  Hope this is helpful.

Thanks so much for that, Jim.  I appreciate it.

It turns out, after exhaustive troubleshooting, that it was a case of ASN not playing nice with FSUIPC, and/or ASN not liking my virtual memory settings. 

This was not, as it turns out, any CS issue at all. 

Got it fixed and several test flights have confirmed it is fixed.

Hopefully you enjoyed the flight from Cleveland to NYC!  I love that MIP4 STAR.  I usually fly it with just the Nav radios and the ADF.  It is a busy one when you are one guy flying three crew positions! 8-)
