Most likely you're using the wrong or an outdated/buggy include file for the ISR vector definitions. There were some with wrong vector address definitions. Therefore the IRQ is issued but the ISR is never called as its address is stored at the wrong place and the unexpected IRQ vector is called instead. You can look at he linker list file to veryfy that the vectors are at the right place.
If all is correct, please tell us which MSP you're using as things are different between different models. Sometimes VERY different.
