FM10 and Plug-In loading in FM 8.5

[Ivan Granger]

I've got a strange question for the group--

After limping along for too many weeks with the pre-release version of FM10 on one of my Macs, I finally installed FM Adv 10.0.1.

I realized there was a problem, though, when I tried to launch FMP Adv 8.5 and discovered that a couple of old plug-ins I still depend on suddenly wouldn't load. Old copies of ExportFM and SMTPit that had been loading in FMP 8.5 just fine, now suddenly will not load. The only obvious change I made to my system was installing FMP 10.

Does anyone know why the 10 installation would affect plug-in loading for 8.5?

More importantly, can you suggest a fix that will allow them to load once more?

Thanks for any help.
