Hi. Yes . I have done this and found my files in version 2.3 but it lasts for only 30days and I have paid a full subscription via apple app store. Yesterday they finally responded saying that they had missed my messages and directed me to a licence number but it was only for version 3. which will not open. This morning in despair I bought Tap forms for mac and transferred all my files to that and a developer who responds to emails. iDatabase an expensive mistake for me.
Thanks for your interest in this issue.
