I just reinstall my 737 from scratch. I keep getting some generation code error. I enter the code that was sent to me when I purchased the AC, but that won't work. And it won't let me update to 1.3 so I can install the 800/900 AC. Thanks for any help.Bill M

1] Use the PMDG remover tool here.http://www.precisionmanuals.com/downloads/inc_downloading.asp?iFile=209 2] Install the base and then ALL the current updates as this will no longer require you to use a key or code for it to work.. and do not run flight sim intil you have installed all the updates...Best Wishes,[h4]Randy J.

I removed the 737 using the removal tool. Re installed the base package, Rebooted computer. When I try to install the 1.2 to 1.3 update. I keep getting the error message "PMDGG 737 readme txt could not be opened". And patch won't install. When I look at the 737-600 AC cfg file, the is no entry of the patch.Bill MFS9Win XP pro SP1

Any suggestions on why the patch won't install?Bill M
