since this is the only report I've seen of this issue, do you have problems with other programs? if so, you need more help than Turbotax can provide. Take it to a pro for an analysis. Could be anything from the hardware to malware.
if this is the only app you're having problems with, do you get an error message when opening the app?- contact support
