Unable to Open Files

I recently purchased a product key for Scrivener and am attempting to open a project file but every time I try, I keep getting the following errors (note, I replaced the name of the file with XXX):

The project “XXX” could not be open.
The project you are trying to open was created or saved using a newer version of Scrivener than the one you are currently using. You will need to update Scrivener to open this file.
Try selecting “Check for Updates…” from the Help menu to look for updates.

My version is currently the most up to date version of the software. The file that was sent to me was most likely (though I cannot confirm this) created using the MAC version of the program, but it should still be able to open with my version as it is still as .scriv file. Any advice on what i need to do in order to open this file?

The latest version on the Mac is Scrivener 3, which uses a different project format from the current Windows release version.

Either ask the person who sent the file to convert it to the older format with the File -> Export -> As Scrivener 2 Project command, or download the Win Scrivener 3 beta from here:

There can be many reasons for this. Maybe the product key you entered may not be a valid, or maybe the file you want to open is corrupted, did you try to open another file?
