It looks as if the TextQuick 1.5 launch has been marred by a few hiccups with the Handango web site. I uploaded TextQuick 1.5 to them, and requested that it be offered as a free upgrade to all existing customers.
I've had some reports back from existing customers saying that they have been unable to obtain the latest version of TextQuick. I'm not sure why the Handango site is not offering the update for free. This is my first time going through this process so the problem could be with how I've configured the site, or it could be with Handango.
I've emailed Handango requesting some help, and they've said they would get back to me in a couple of days. In the mean time if you have any issues with obtaining TextQuick 1.5 simply download the trial version, and drop me an email with the IMEI number, including dashes as shown by TextQuick. Select “Options”->”Register” from the application menu. Include some proof of purchase, for instance the email address you used when you originally purchased TextQuick and your transaction number / receipt email. Send the email to email@example.com.
