old version of rfactor to work without uninstalling FSR

[Tomesions]

Hi
I really want to know if there is a way of getting my old version of rfactor to work without uninstalling FSR.

At the minute I'm not too sure what causes it but it goes blank when i try to load the old version.

I love the FSR mod but would still like to use other f1 mods for rfactor.
I apologise for the poor description but any help is appreciated.

Thanks in advance
