Error in SOPC : The given combination of PLL input and output cannot be synthesized.

hi, I just aquired a new PC and I'm trying to generate a SOPC design which was previously generated on another PC. However, when I open the SOPC design on the new PC, there is a error mess...

I tried creating a new design, however, as soon as I add the "DDR2 SDRAM Controller with ALTMEMPHY" to the design, the error message appears.

Also, I'm using the Cyclone III device, not the Cyclone IV E.

It seem to me that there must be some settings in the QuartusII tool that are causing this error. I'll submitt a service request for further help on the matter
