Strange building problem with SOPC builder

Hi,

we have been successfully generating many NIOS II designs with the SOPC builder over the last 8 weeks. Today however, the following error apears when trying to generate a system (with two NIOS II cpu's)

I hope anyone here knows what is going wrong, because I have no idea what the error is.

Thanks in advance,

Jos
