Thanks for the Help

Thanks all for the help in trying to resolve my problems with V-Speeds being deleted. I uninstalled an reinstalled all of the PMDG aircraft. I was having a problem when I pressed the activate A/T (pressing the screw head) during takeoff roll. When I pressed it the V-Speeds were deleted (no changes to weights, flap setting as entered in the FMC, etc...). The reinstall seems to have solved it. But wanted to thank all for the help.
