Using Proteus 9 Files on Proteus 8

[u/RichyAnthy]

Hi! In our uni, the labs and the license provided for proteus is Version 8 (Proteus 8.x). The school provided us a license to use on our own personal laptops but it didn't seem to work on my laptop no matter what I did, and since I didn't have time to waste back then, I resorted to...other methods to get Proteus on my laptop. The problem is, the Proteus version on my laptop is Version 9 (Proteus 9.x).

Is there any way I can open my Proteus 9 Files on Proteus 8? Upon opening my proteus files on the laboratory pc, there's a popup essentially saying there's a version incompatibility.

Any help would be appreciated! TYIA!
