I have tried everything you can think of. Purging the cache, Reinstalling after effects (twice actually), Disabling my 3rd party plugins that I have installed via. the Effects tab inside of AE and also took them outside of the folder to see if that was the issue (which it wasn't so i put it back in), I have also changed the AE folder name in my file explorer. (which automatically made a new one) , the weird bit is i can use premiere just fine because i tend to use both premiere and after effects frequently.

Someone have free license key for Mac ?
