TURBO TAX Says I used up all my activation licenses BUT I only have Used it on One Computer ERROR code 603 wtf

I am having the SAME FCKING problem.  TT keeps asking for my code after each and every freaking update then NOW it says I have used up all my licenses even though I'm only using it on ONE computer.  WTF. 

This is ridiculous. Does someone have a fix for this. SO STUPID TT why the F do I have to re-enter my activation license each and every time and now you tell me I used up all my licenses even though I am only using it on ONE FREAKING computer.  I swear if I have to buy another TT that will be it with TT.

I had this problem a few years ago and finally figured out it was due to a system configuration change.  By simply plugging in a USB flash drive TT for some reason decided the system was different.  All I can recommend is think about what you may have plugged into your system since TT was last allowing you enter the program, and try to remove the device.   Or if you made any configuration changes (swapped keyboards, mice, usb drives around, etc).   When I finally figured out what my issue was, simply pulling out the USB flash drive solved the problem, and if I plugged it back in and started TT sure enough the license screen popped up again.
