multiple files suddenly gone corrupt

[ned.morris89]

Hi, 

I am in a bit of a stressful situation. 

I just went to open some of my files in Fusion and they would not open and got the alert that they are corrupt. 

I have tried clearing cache, repairing fusion and still cant open them. 

I found a workaround where I can open them in the browser, then click the "open in fusion" button and it will open. But as soon as I make a change and try to save, Fusion crashes. 

Any help would be much appreciated.
