Hi Dick,
There is another possibility that can cause it not to work, though I have never run into someone who had both issues at the same time...but it is possible. I think we can solve this.....without it you would not be able to use any of the RTMM AI Shipping packages which are quite nice. If you PM me your email address, I can work you through it and see if we can solve it on a direct email basis.....it is up to you......let me know.
