Previous versions of Guitar & Drum Trainer are no longer available except to licensees. The support path is now for version 4 only as bugs from previous versions are now fixed in GDT v4.
If you are a licensee for GDT v2.3 or v3.x and wish to download your version again, please contact Renegade Minds to email you the proper download link. Make sure to include the email address you used when you purchased your license.
Thank-you,
Renegade Minds
