you for reaching out to the Community regarding your issue, although I am sorry
to hear that you are experiencing issues with your file. I believe you updated to 34.15 and are experiencing issues now correct? My first recommendation here is to perform a mondo patch to the previous patch to be able to get your file opened to start. I'll leave steps down below on the mondo patch.
Once you install the mondo patch let us know if you're able to get back into your file. From there we'll work on getting the program updated.
