I did the .99 cent up grade. I registered. Have not seen any change in my app. I have completed the practicedemo several times. Now what please.

Did you have problem when you tried clicking on "multiplayer" from Dogfight home page? It should take you through prompts from there.

The upgrade unlocks all multiplayer content and game modes.

There is no change in the app when you upgrade as far as I'm concerned. Plus, I think you should have done the $4.99 lifetime upgrade. That way, you won't have to constantly pay over and over when it tells you to upgrade. At least that's what I remember. Anyway, once you upgrade there really is no change. Only thing is you can continue to play multiplayer. You can now play as the new plane you purchased. So umm yeah I have no idea what I'm saying here lol

Yes it will not let me log in on the multi player page. I am using a tablet could that be the reason. It won't let me put my user name. Please help. I feel like I was ripped off for my .99 cents lol

No, the tablet should work. What kind is it?

So when you press on the bar that says "email", does the keyboard come up? If it lets you type, maybe the text just won't appear. Try typing the email anyway, and then do the same with your password. Press enter, and see if it works. If it doesn't, install a new keyboard. That works most of the time.
