Hi, I have been having a lot of issues trying to run pro tools...first I installed Pro tools essentials and then had to upgrade to M-Powered. I purchased it online for 150 and then found out I had to get an ILok...So i stop by the Sam Ash store and buy an ilok for 40 bucks...then once i click authorize it says im missing a .dll file and that I should reinstall m-powered...once I try to uninstall it it gives me an error saying it only works with Windows Xp SP3 and Vista...I have windows 7 but it was working fine before when I had essentials. Can someone please offer help, I am really starting to lose my mind now
