I'm concerned that you can't import audio or photos. That would indicate some serious issues at your end, and not something we can likely help you with here on the forum.

That is assuming that by audio you mean WAV files and that by photos you mean photo that have been resized to no larger than 1000x750 pixels in size.

Other than that, Premiere Elements 9 works great on Windows 7. I had no problem running it on my Windows 7 machine.

Although version 10 runs even better and version 11 runs better than any version of the program, especially with AVCHD footage.

You say the program runs slowly during the editng process. What type of media files are you editing? (I assume you're not working with photos or audio files, since you say can't load them into a project.)

What model of camcorder is your video coming from and what format and resolution is it? Did you use Premiere Elements' Get Media tools to get the video from your camcorder to your computer?

When you started your Premiere Elements project, what project settings did you select? If you selected the correct project settings for your video you will NOT see red lines above your clips when you add them to your timeline. Is that the case in your project?

As I indicated in my first post, photos directly from cameras are way too large for use in a Premiere Elements project. For high-def video, your photos should be not be larger than 2000x1500 pixels in size.

Music from iTunes can usually not be loaded into a video program in its native format because it is copy protected, and trying to do so will throw up an error code. iTunes has relaxed these protections a bit, but it's still very common for this to happen. The solution is to output the song(s) as CD and then rip them back into the computer as an MP3. This will override the copy protection. (An alternative is to use Amazon.com as your music source, since they use almost no copy protection on their music.)

It's pretty simple.

If you want to use a photo in a high-def project, you need to use Photoshop Elements or Photoshop to size it down to 2000x1500 pixels (at 72 ppi).
