FsP worked fine with hotfix but other things with the sim screwed up, and thus I went back to v2.5 w/o hotfix.

You didn't mention whether or not you have the full P3D installer that includes the hotfix. That way you can do a new installation. Maybe those
other problems not related to FsP would go away.

Fsp doesn't recognize regular v2.5. Thats the problem.. The
critical error comes up and says version not recognized. Is there a workaround for this as I suspect many potential customers are in the same boat thx

Maybe you can email Dan and ask him if you can get the previous version of FsP that works well with the original 2.5 version
