I think you mean DPED Version 1.10. http://www.simviation.com/cfs2utilities1.htm

This is still usable with FSDS2 aircraft but it can't read the MDL file to create the wireframe image. I know someone was working on an FSDS2 plugin to create DP files but I'm not sure of its progress. The only way over it in the meantime is to produce a version of the project with FSDS1 (if you still have it) & use DPED to base the DP file on that. I find it much easier to do the preparatory work in FSDS1. It only needs to be a rough outline of the project which can then be imported into FSDS2 for finishing off. This is fine providing you don't need to reposition the model or do any drastic modifications.
