I did this:
Open Recent>> to open my recent 0.9.2 project
and then did some changes to it, and saved it on 0.9.3 GS
and it works on the GS itself, but when I tried to publish to adhoc distribution on an iPad
it just won't open.
Tried the solution
opened showed package contents
I found myusername.guser
(for example sake myusername is not real, replace it with your own, real username)
now I replaced myusername.guser into test.guser
and tried it again on 0.9.3
same problem..
any fix to this?
thanks

In my Trash, I saw GS 0.9.2 and then I dragged it back to my desktop,
reopen my backed up file (that I did not save and modify on 0.9.3)
and succesfully built an ipad adhoc game..
the problem then MUST lie on 0.9.3
please kindly fix!
Thanks
