After downgrade it says i am using incompatible version
After uninstalling the upgraded version 15 and re installing version 12 on all machines. ( Because they all upgraded automaticaly, yes I know how to stopit just forgot) I tried to conect remotely with my licensed version of 12 to the resently downgraded 13 and it told me I hav an incopatible version **bleep**? I just checked both machines and they both have the same version. What is wrong?
