Aperture won't open because of newer version of library
I have both Aperture (3.3.1) as I photo (9.4.3) on my Imac. I can not upgrade to Aperture 3.5 as the Imac is too old and cannot have a higher OS-version then 10.7
Both Aperture and Iphoto use the same Aperture library (3.3.1).
The upgrade to Iphoto 9.4.3 was recently. Once installed it mentioned that it had to upgrade the library (aperture).
Eversince I can not open Aperture; I always get the response : cannot be loaded because it is from a newer version of Aperture, although both program and library have the same version.
I tried the repair permissions, repair database and rebuild database... It does not solve this issue the next time I open Aperture.
how can I bring back my library to the correct version? as I have the feeling that the upgrade by Iphoto 9.4.3 brought the library to a higher Aperture version.
Imac Intel, Mac OS X (10.6.4)
