Bought iMovie ('11) on App Store, are older versions still available?

I bought it when I had a Macbook Pro (early 2012) and an iMac (late 2012) - both running Mountain Lion - but I recently sold both of them in favor of a 2007 Macbook (white) which I've added RAM and a nice SSD to (it is running Mac OSX 10.6.8). Unfortunately, my iMovie license is all but useless since the App Store only offers the newest version.

Is there a way I can get an older version of iLife (or just iMovie) from Apple without having to buy a physical iLife disc?

Thanks in advance for your time.
