Ok misjka, you just dove into the deep end of the pool.

You'll want to install the "merged" version i.e. AEP+PF before you continue the updates.
You can find the patches up to 4.04m (use the ones with the "m" in the name - m=merged) here ....

alternatively here ....

ATM I cannot trace the rest of the patches, maybe you can find them on the fz.se site.
Hope this helps.
