Error code

SOLVED

I am just finishing entering in history mode. I installed Microsoft 365 business and integrated with Sage. OneDrive synced with my files, so when I tried to open Sage again, it didn’t work, throwing an error code that couldn’t find files (I assume because it was synced). I then unlinked my pc from OneDrive as recommended by Sage help. Now when I try to open Sage it says “cannot find .sai file”. I managed to download the .saj file and data file before I unlinked, but also didn’t find the .sai file. I can’t access my Microsoft business account now either (which holds my backups). 
I would like to phone Sage for help, but don’t know how to find a contact number. Help?!
