4. PP 2004 crashes when opening old PP document with audio

Hello,
I'm having trouble opening PowerPoint documents created in Office X
using Office 2004.  If the document contains links to audio files
PowerPoint crashes before completing the startup process.  PP docs
created in Office X that do not contain audio open fine.  I have:
1. Repaired permissions
2. Checked for and deleted corrupt fonts and font caches
3. Trashed PP prefs from user and main library folders
4. Checked and made sure audio files were 'read and write' enabled

BTW - These PP docs still open fine in Office X.

Thanks in advance for any assistance.

5. my PPT 2007 open blank slide when try to open from website

6. trying to open 15 year old superpaint files

I had superpaint MS1.1.  First on the 512K mac and then on the SE 30.
I can't for the life of me open those documents.  I had them stored on
a zip100.  I recently found someone who could put that to a cd.  The
files are not recognized as superpaint files by GIF converter (not
recognized at all).  I tried adding the ".mac" to the end of them and
was able to open a macpaint demo file (boneless chicken ranch).  But
the superpaint files remain a mistery.

I worked hours on some of those docs, that I would love to see.  Is
there some way to open them? ( I have iMac G3 now; OS X)

7. Excel 2004 tries to open every file in the documents folder

8. Spinning wheel when I try to open a document or save

I'm running OSX 10.4.3 and word 2004, just this week I 've found I can't open 
any documents, Word will launch ok from the dock and a new black document is 
created.

If I try to save the document I get the spinning wheel, If I try to open an 
existing document I get the spinning wheel.

Has anyone had this problem?
