Perhaps it would be easier to get the help you need if told us what version of Studio you're using, when the error occurs and what the exact error message is?  Maybe even tell us how you created the project... so was it a package created by others or did you create the project yourself from the original source DOC.  I presume when you say DOC you really mean DOC and not DOCX or some other format of document.

It's far more helpful to get help when yo provide some information rather than close down the question before anyone can reply by just saying you tried everything there is to know already!
