TMS570LC4357: RTI COMPARE INTERRUPT NOT HANDLED .

Hello,
I'm a new to the Hercules Launchpads.I wrote a small code to test the ability of the RTI to generate a time base and I'm currently facing a predicament of 
an unknown origin.
The RTI generates a compare0 interrupt,as indicated by RTIINTFLAG register (bit 0 is 1), but, apparently, the VIM doesn't handle it .
I've cleared the IRQ bit from CPSR, enabled the channel 2 interrupt from REQENASET0 (in VIM) and enabled the interrupt in RTISETINTENA (RTI).
I'd like to mention that I've made a similar program concerning GIO interrupts ,the only difference was the channel and, of course, enabling the interrupt in the
appropriate GIO register.
I've also used rtiInit() to rule out potential initialization erros.
Would you kindly provide some advice regarding the cause of this ?
