Hello Phate, Could it be a problem with the DDR2 controler licensing? I think if you want to compile DDR2 IP then you must have a valid license. If you have full version licensed for 9.1 SP1 this might work. What about Quartus 10? Do you still have full license or valid IP license installed for DDR2? If yes you may enter a support case with Altera. If no, please make sure if DDR2 compiled with out IP license would work in Q10.

Or when you change the Quartus version do not forget to regenerate your DDR2 core again. This sometime makes the problem. All the best.
