FSX AI Flightplans Query

Hi there,

I have recently copied over my FS2004 AI Aircraft and FS2004 Traffic Files, to FSX.
And I used the AI Flight Planner Program, to Bulk Convert my FS2004 AI Traffic Files to FSX AI
Traffic File Format Files. Virtually all the FS2004 Traffic Files, had the @ Symbol in the Flightplans.

But when I did a check of some of the FSX converted AI Traffic Files, the @ Symbol had been removed from them.
Is there an option in AI Flightplanner, which allows a Bulk Convert of FS2004 Traffic Files, to FSX Format, without removing the @ Symbol ?

Any help and info would be appreciated

Eddie
