PMM_setVCore(PMM_CORE_LEVEL_2) gets stuck

Hi,

I am having problem running TI's example code "C1_LedOnOFF" in Debug mode. Execution halts at following lines in pmm.c

    //Wait until SVM highside is settled
    while((HWREG16(PMM_BASE + OFS_PMMIFG) & SVSMHDLYIFG) == 0)
    {
        ;
    }

I am using following hardware / Software

MSP-TS430PZ100USB

MSP430F6638

IAR Embedded workbench IDE 6.40.4

just couple weeks ago I was running same example and every thing was running just fine. now I can not get past this point. The only thing I remember doing is that my IAR 30 Day evaluation license expired so I updated it to a valid license.

please check the screen shot for more insight.

Any ideas help will be much appreciated.
