I downloaded Lion onto my Mac, and now cannot open or access any of my Microsoft word documents or Power Points. Is there a fix for this? I need my documents

If it's because you were using Office 2004, the eight year old version of Office that was written when Intel processors were not used in Macs, then there will be no fix. Lion dropped support for PowerPC applications, as has been widely reported since Lion's release last August.

You can upgrade Office 2004 to Office 2008 or Office 2011. You can use iWorks 2009 that can open Microsoft files. You can use a number of free applications that are also capable of working with Microsoft documents. You can go back to Snow Leopard, if you have a backup. Or, if you have an external drive or room to add a partition to your current drive, you can install Snow Leopard on it.

Search these forums for more information. If this is your issue, it's been posted and answered several times a day since August 2011.

With Lion you will need to install Office 2011 to open your Office documents.

Try downloading free program Neo Office: http://www.neooffice.org. I don't have any files to try it for you, but it's free and very useful. It's going to warn you about Lion combatibility, but works anyways.

Your documents are fine, you just Lion - compatible programs to work with them.

In addition to the others' suggestions I recommend Pages, Numbers, and Keynote - genuine Apple replacements for Word, Excel, and PowerPoint respectively. They can all read and save MS compatible formats.

Office 2011 is an option, but Apple's solutions have been developed to be more suitable for Lion. I don't miss Office one bit.

Have you tried LibreOffice. LibreOffice is a "free" software much like MS Office. There is a Macintosh (OS X) version. LibreOffice can read and write most MS Office files and a lot of "ancient" file types. It is a good replacement for MS. Office.
