the version of the file being opened is not supported by this software version

I have an autocal I bought used and had unlinked. I just got a csp5 switch and tunes. I downloaded both v7.5 and v8. when I open efi live file explorer and try and drag the tunes into it I get a message that says the version of the file being opened is not supported by the software. as far as I know everything is current with the programs as I downloaded it last night. Were do I go from here.

Has you Autocal been linked to your tuners Flashscan?
Your Autocal needs to run software that is compatible with your tuners software - confirm with them what versions you require. It may be a later pre-release version / Release Candidate version that they are running.

I got it. Had to download the updated 7.5 and 8.2.
