I bought a new computer a couple of months ago, didn't bother to reinstall PMDG's 737 series, just reinstalled 747-400/400F.Now I decided to reinstall the 737, do I need to contact support to show that I'm a paying customer and so on?You know for validation and stuff.....Best regards/

The 737 does not have validation software like the 744 does. You can reinstall no problem, just be sure to read this first:http://ops.precisionmanuals.com/wiki/PMDG_...7-400.2F400F.3FLook at the workaround below if you've still got the 744 installed.

Better do the supported action, uninstall the 744 then install everything from scratch. ;-) Thanks
