Power Point Presentation

[DFCI]

Hello,

We prepared a Power Point presentation for my daughter's wedding and it came
off very well. The file is quite large and ever since the presentation was
delivered I am not able to open the file to show it again.

Upon opening it, here's the error message that comes up:

Powerpoint can't open the type of file represented by C:\Documents and
settings\my documents\wedding slide show\.ppt

Does anyone have any suggestions as to how I am able to deal with this awful
situation?

Please advise!

Thanks!
