We believe that if one user has a question, there could be more users who may have the same question. This is why many of our support forum threads are public and available to be searched and viewed. If you’d like help immediately, feel free to search for a similar question, or submit your question or concern.
I see that the form in your account was moved from a guest account to yours. Since there were submissions received while the form associated with a guest account, the uploaded files for these submissions are also linked to the guest user. I have now transferred the ownership of the files to your account. You should be now able to download the files without any issues.
If you need any further assistance, please let us know. We will be happy to help.
