I've got a power point issue of my own. The file is large at 78 MB, but I did purchase the space upgrade, and when I tried a test with a much smaller .ppt file, I had the same result. I have successfully uploaded the .ppt, and sent the link to the editor, but when I go the post and click on the .ppt file link, it just takes me to another copy of the post, not to the power point. The post is located here:

If someone can take a look and see what I'm talking about, I'd appreciate it. I purchased the upgrade pretty much solely to host this .ppt and send the link to friends and family, and I put a lot of work into the presentation, so I'd really like to get it up and running.
