Thanks for trying that.
I appreciate that you also used the Windows format as it is nearly foolproof.
After speaking to our Director of Engineering and tabulating cases where this has happened we can say that each case is a little different.
That is, not all customers who have updated the Bridge II to 3.6.2 have lost their artwork.
Those that have seem to have different causes for this.
One suggestion that seems to have worked well is to power cycle the entire network.
As well, have you only been having trouble with MQA files only or other files?
As I said before we do take this very seriously and want to get you back up and running.
Let me know if the power cycle is successful.
