Analysis and exporting to Pipelink

Hi,

I am using Windows 7 and Bentley AutoPIPE V81 (SELECT series 4) Advanced Edition Version 09.05.01.05.

I want to know is there a limit for sets/quantity of load cases that AutoPIPE can export to PipeLink (I intend to export the piping model to STAAD.Pro). I have set up a number of load cases (including multiple user cases). AutoPIPE was able to complete the static analysis of the piping (I can see the code stress result). However, when I tried to export the AutoPIPE model to Pipelink (File-->Export-->Model to STAAD Using PipeLink (*.pipelink), the small dialog box appears (showing how many supports being exported). It did not complete the export process that AutoPIPE crashes. What can be done to remediate this?

Please advise way forward. Thank you.
