reinstalling cubase pro 9

Hi…I know this is a dumbass question to ask but…I got cubase pro 9.0.20…which is buggier then 9.0.10… on my mac…I would like to revert back to the earlier version…do I just delete the 9.0.20 and do a reinstall with the installer I got when I first got the program (9.0.10)…would there be any problems on a reinstall…or will the elicenser not allow me to?

thank you

I have just done the same thing on Windows. I uninstalled 9.0.20, reinstalled with the original 9.0 installer then installed 9.0.10. The 9.0.10 is not the full program.
