[R] error from pmvnorm

Hi all,

Can anyone tell me what the following error message means?
" Error in mvt(lower = lower, upper = upper, df = 0, corr = corr, delta = mean, 
:  NA/NaN/Inf in foreign function call (arg 6)"

It was generated when I used the 'pmvnorm' function in the 'mvtnorm' package.

Thanks a lot.
