How do I know I have an upgradable version of Logic Pro X?
Less than a year ago, I bought Logic Pro X (10.3.1) from a 3rd party for under $90. The page said nothing about it being some special non upgradable version, and now I suspect it is. Is there any way to know for sure (like a serial #)? Is there any way to upgrade at a lower price, if so? thx
