why do my documents sometimes turn the text to jibberish, then i lose them????

Could you paste an extract of the problem text here? Just a couple of lines?

It could be something to do with the fonts to display the text but more likely is that the text program (Word?) somehow does not recognise the file format and tries to open it as a plain text file. This means that it will try to display any meta-data in the document as clear text which is unreadable.
Could something have gone wrong with the file-associations on your PC? Does the right program open if you double-click a file?

DOC files are MS Word files and Word should open them correctly.
WPS files are MS Works files and you may need a converter in Word to be able to load these files correctly (I've never used them).
PUB files are MS Publisher files and should (as far as I know) not be opened with Word. Only MS Publisher can open them.

Try sticking to one file format to work with, if you can, by converting WPS files to DOC files (Use File -> Save As function in Word).

Hope this helps.
