Cant download older versions of after effects!

[Gregory5C53]

Hello, I am trying to reconstitute (and remaster) an AfterEffects project that was created with version 5.5. NOT CS5.5 which is in fact version 10.5, but version 5.5 of AfterEffects that existed in 2002. If that version is not available, what versions exist that would allow me to progressively upsave the project until it becomes compatible with any current version of AE? Thanks.

The last version to open such old projects was CS6 and those projects can still be opened in current versions.
