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.
