Hey GuysAfter changing my system the PMDG runs now realy smooth! ;-)) but I had a problem activating the autothrottle ???? ( I transferred my whole FS to the new hard drive, copied the FS registry into the reg and off I went until I tried activating the autothrottle.Any ideas how to get set with this?

May not be a bad idea to uninstall PMDG using the uninstall app. which can be found on PMDG's site. It does't take much to corupt a file when transferring the contents of a HD.A reinstall will mot likely work well here, providing your system is stable.Sometimes a system seems to be stable but may have minor memmory defects.Google memtest86 and download the new windows version. You create a 31/4 boot disk and let it run overnight.Many times a new system requires new memmory, if it's bad in any way your dealer will usually take it back if you tell em it failed memtest.It would help more if you would state whatever changes etc. you made to your setup.Regards
