I know this is my problem, and not one with AppGameKit or the Play store, but I'm not sure how best to proceed.
Basically I wrote an app a while back, which I have recently updated and compiled into an APK using the online tool provided by TGC, but apparently I've used a different keystore file for the new version and the store won't let me update it.
I'm pretty sure I have lost/deleted the original keystore file (although I don't remember ever using more than the one I'm using now) so I don't think I'm going to be able to just recompile using the correct keystore file.
I don't really want to just create a new App with the same name as that wouldn't allow existing users to update via the store.
Does anyone here have any suggestions as to how to sort this problem out?
Thanks in advance
