Hello,

I have tried to open my flash files this morning and none of them will open. Instead of opening, a pop-up appears with ‘Unexpected File Format’ in it.

Also, all of the Flash files I have published are now displayed with msDos icons rather than the grey flash icon - they will not open either.

Another error message I see is ‘the following javaScript error occurred’ and then a line telling me that my file could not be opened.

If it is of any significance, my computer has recently installed some updates - one of them I think was a javaScript update.

I would be incredibly grateful if somebody could help me out - and hopefully tell me that I have not lost everything I have made!
