Sounds like you are, we will check on this and get back to you.
Rita, I assume you downloaded version 4.0.5 which should resolve the issue so I'm closing this ticket.  One thing I noticed on your app folder is that it is HUGE!!!  Almost half a gigabyte.  For people with a device that only has 16GB you would be occupying a significant portion of space.    I never downloaded your app because it really is way too big, if you do end up with a problem, it would be best for you to create a one page sample, this way we can identify the issue a lot easier.  In the meantime, I would look at your graphics, videos and audio and see if you can reduce the overall size of your app.
Hi Jen, sorry for this mess.  All you need to do to fix this latest issue is to go into the App Folder and delete a file called InteractApp.rdb.  You will see this file is zero bytes, the last update created it.  Once you delete the file your app will convert successfully and you should be all set.  I am working late tonight so let me know if you need any additional help.
Please download the latest update 4.0.5 which was just released. This should resolve your issue.  Let us know if you still have a problem.
You would have to use something like DropBox, to send use your app you would have to compress your application folder which is under your Documents folder under the folder called InteractBuilder.  Once you compress your folder you can copy it to DropBox and then share the link with us.
