Version 7? That's pretty darned old. Have you tried ebay? Short of that, you can still purchase AE CS6 -- aka AE Version 11 -- on the Adobe Web site. You'll have search quite a bit to find CS6; they're pushing Adobe Creative Cloud really hard.
Thanks, the instructions say 7.0 or newer so I guess any of the new versions will work

I doubt you will actually find any templates for versions that old. Most creators will no doubt at least use CS4 or CS5...
The current version is version 13. That is certainly newer than version 7! You can get it from Adobe for less than $70 a month. This also gets you access to the entire Creative Suite. (Also, several versions back are available. You can run as far back as version 11 of AE, if you want.)
