I have PT 2005 installed and my trial period has elapsed. My question is this. I'm going to buy PT 2006. Will I have any problems after installing PT 2006 with the software attempting to tell me the trial period has expired before I'm able to install a license key? The reason I ask is because, now that my PT 2005 trial period has expired, the program doesn't even give me the "enter a license key" option anymore, when I try to start the program, I briefly see the box where I could enter a license key, but am unable to select it, I then get the two "expired" message pop ups and that's it. Thanks.
