These are located on our local server. Going thru several issues with IT at the moment that may be related. Altho its strange that the file saved yesterday without an issue. I tried to open this file from another computer on the network but ran into the same issue. looking like a corrupt save.
The computer issues today are related to some windows updates not playing well with my computer for some reason. Due to size (500 meg) and customer data its not possible to send the file.
Note if the extension was edited it would effect all files, not just a few of the files from yesterday, that’s why I’m thinking/Hoping its the Windows update.
Once IT guys get finished with my computer I’ll check back if there are any changes.
