We created project in Quartus software version 13.0 sp1. This project includes FIR compiler II megafunction block. When we are trying to open this block in Quartus 12.1 sp1 MegaWizard Plug-in manager doesn't open.

Previous versions of quartus generally wont open designs created in future versions as often new features are added. You will have to regenerate it in 12.1 (which you should be able to open in 13.0).

Backwards compatability means newer versions can load older designs, not the other way round.
