Hello.

I am very sorry that I can not resolve this issu for you. My problem is one of convincing Adobe to reset my Digital count ... after 3 weeks there is still no resolution to my problem.  Perhaps if you continually go through CHATS and make a nuisance of your self, maybe then they will look at your problem.   Good Luck
