I'm sorry to hear that you have trouble running PSTouch.
When you launch PSTouch for the first time it's important to have network and you're signed-in with your play account. Please try this...
1. Uninstall PS Touch
2. Reboot the device and reinstall PS Touch via
the play store app
3. Launch PSTouch . For the first launch of the app you need a network connection and signed in with your play account
Hope that helps.
Thanks for the quick reply! I tried what you suggested but I'm still getting the error message. I'm installing from the play-store app after an uninstall and a reboot and I definately have network while I am doing it.
It states in the play app that this is "Purchased" and I have the billing info and receipt in my gmail. I'm wandering if I entered the dedit card details incorrectly when I added this card to my google wallet. It's the first transaction I have attempted on this card and there is no details of the payments leaving my account when I check my balance online. Apps I have purchased the previous day on a different card are showing already but not this one?
Could you also check if you have the correct date set on your device? The important part for the first launch is that you have the same google play account running on your device as you have purchased PS Touch with.
