If you're one of the lucky ones who've discovered the value of using Action Scripts (to digitally watermark lots of photos, of course) and your software of choice is Adobe Elements, you should read Erin's blog at Texas Chicks.

It seems that purchasers of Adobe Elements 9 on the Mac App Store are NOT allowed to install action scripts through the Effects Palette.

Be sure to read Erin's blog (she's an Action Scripting Goddess for those using Elements). Just incase you're lazy... the solution is (a spoiler alert?); buy direct from Adobe or Amazon to avoid this issue.

Thanks again to the Texas Chicks!
