There was an error accessing c:\users\media\AppData\Local\Temp\sftch\EW425154539\ppv87D5.pp

The path in your error will be similar, but the last part of the path will change with each new schedule you build. 

In order to resolve this issue, you'll need to Open the PowerPoint file you are trying to use in EasyWorship 2009 with PowerPoint. 

Click file, save as and save the file as a ppt file instead of a pptx file. The PowerPoint will then import into EasyWorship. 

This issue does not occur with all PowerPoint pptx files, but some pptx files have this issue in EasyWorship 2009.
