Tempo Problem with older .cpr Cubase 6.5 files

I finally upgraded to 8.5.

When I open my old projects (recorded with Cubase 6.5) they are all playing much faster than they were recorded.
I do have a new audio device than I recorded with originally.

Went from a m-audio AP192 to a Focusrite Scarlett 2i4.

Windows7 64-bit

I’m preparing to upgrade to Win10 and wanted to work out all my software kinks before the upgrade.
Thanks for your help.

Your audio interface has to be set to the same sample rate as the projects were recorded.
