What kind of document?

On Windows or Mac?

File corruptions can happen. It has not happened to me recently unless the app terminated unexpectedly (power outage) and the file was not properly saved & backed-up beforehand. 

Also missing fonts might pose problems if the document was created on another system platform.

Please let us know which program you are having problems with. Someone will be along to move this post to the appropriate product forum, where you are more likely to get an answer to your question.
