I am having a problem and wondered if anyone had a workaround or is this some kind of bug. I have had the problem in the past and it was never resolved but yesterday it started to work okay, only to find tonight it has stopped working again today.

I have created a word document and uploaded the file yesterday and mapped all the fields and it worked fine. 

But now the problem I keep getting is after uploading and mapping the fields and clicking to have a look at the preview I don't see a preview but a file is automatically downloaded called print. 

Anyone had anything similar?
