einstein.cubed:Do I need a license other than my regular license for non-bet to be able to install it? Thank you.
If your referring to the free license you got in your email when you originally downloaded Blink, you can use that in the Beta 3.1 version also. If not, refill out the Blink Personal Edition registration form again, get the new free key they will email to you an then use that in the Beta 3.1. This is what I did.
If you are using a paid for key, simply go to the top of the main Blink screen, go to help, then to license management (I think it is called this) and then select to "transfer license". This will remove it from your current installation and allow you to use it elsewhere.
Uninstall your current version of Blink and then install the Blink Beta 3.1 version.
If your concerned with losing your settings that you have in Blink now, refer to this post on how to save them before uninstalling Blink: http://forums.eeye.com/forums/t/47.aspx
I hope this helps you. :)
