How to download through Mac App Store if on 10.6.8?

Hi!

I got a clean new install of OS 10.6.8 on my laptop (i CANT upgrade to Lion, as i NEED Rosetta for my old Imacon scanner software).

Previously I purchased iWork components through App Store. Now i can't download them - there is no download button, only a "OS 10.7 required" message.

Now, as I said before, i don't wan't and can't upgrade as it will negatively affect my productivity.

Does that mean that I lost access to my legally purchased Apple software?

Even if i try to find a trial version somewhere, I dont have a serial number, as, again, I purchased iWork on Mac App Store.

Is there any solution for my trouble?

Thank you!
