I don't know where else to turn to but I am unable to open my Sage 50 Pro Accounting 2020 program on my computer.  It shows that the program is opening, then it tries to open my company file and this is the screen message I get:

Cannot open company file 'C:\users\Lenovo\Desktop\ my company name  .xlxs.SAI'  A required data file is missing.  Check your data directory to be sure the files are there.

I only have the one company on my accounting package but even if I wanted to start a new company, I would not be able to as the program does not open up.

Any suggestions for me?  What am I doing wrong?

Thanks
