macbook suddenly cannot run powerPC applications...

neye: hi, i have a macbook wich runs like a charm powerpc sofware such as MS Office, de'jabo, etc etc, and i dont know why suddenly starting today it cannot run that kind of sofware... im not sure what i did wrong, last night i only installed darwin ports, xmms, shapeshifter(beta for intel), then used appzapper for removing darwin ports and xmms... well i think i deleted the powerPC compatibility, or rosetta or i dont know what i did and i dont know how to workarround or what to do...
what do you recommend me?

thanks in advance.
