DOH! we've left a bug in for space inversion 2. If you delete the app and re-install it from the app store you'll recieve the upgrade pack for FREE! this'll give you free skins and game modes. (apple won't charge to have it reinstalled) This is for a limited time till we fix this so its ok to tell your friends. http://www.youtube.com/watch?v=ccqeMon9JBw
I confirm the bug. Once the expansion pack is enabled, is it associated with your iTunes account or it would be gone when you upgrade to iPad 3?
Looks like once you install the latest version from app store on any device you get to keep the expansion pack and for future updates too. just seen the updated app description at the app store :-D
I tried to download Space Inversion 1 to try if I like it before I buy SI2 but the message says it's being modified and won't let me download. This has been like this for the last 14 hours!
try deleting the app and re-install it - this sounds like a problem on apples side, it might have been collecting at a point where it changed status. I believe its currently on for sale for FREE today so you shouldnt have any issues. Hope this works for you cygnetseven.
