OK OK!
so I found a solution!! and I'm hoping it works for everyone!
I previously deleted all databases, trashed prefs, re-installed pt, tried to open on a separate drive, spotlight privacy, etc. etc. and still pro tools was taking about 10 minutes to load up.
I then went into the folder Applications>Digidesign>Pro Tools and TRASHED the folder called Log Files. Since doing this I haven't had any problems and pro tools has been opening extremely quickly!
I really hope this works for everyone, this has been such a frustrating experience
