Would you mind trying to export your projects again? Due to a storage maintenance service we did a while ago, your projects might have been affected. We have taken care to restore your work and you should be able to export it now.
If you are still unable to export them, please, file a support request (either from this account or the one you want your projects transferred to) with a link to this post. We will supply a backup of all the work we can find related to your current account so that you can transfer it to whichever account you like.
Share what you think about AppBuilder and Telerik Platform with us in our feedback portal, so we can become even better!
