I have been receiving the error "Element 1013806 became corrupt at some time before this session" etc. I get prompted to create a recovery file however the recovery file and the original file are both rendered corrupt and cannot be opened. I am prompted to send the file to Autodesk to be recovered. A couple of problems - the file is over 100mb and anytime I try to do anything through subscription centre (lodge support request, download latest versions etc), I end up with page not found errors at all URLs beginning with: https://login.salesforce.com/? It doesn't matter which browser I use.
This file has, of course, become corrupt on a major submission date. I am able to rollback to a previous version but am unable to delete the offending element and it's only a matter of time before I accidentally stumble across said element again causing the whole process to repeat.
If I could have directly lodged a support request I would have. I can be contacted directly via email if that is preferable.
Have you opened a support ticket with Autodesk support without trying to attach the file?
Do you have a case number?
Usually they will give you an area you can upload a large file for them to assist.
