Thanks, oh, exalted master! It worked like charm. I've already downloaded the DLL when I posted the question, but the instructions at the Python site say to copy it in the System32 folder. On a side note, you also have to run the Python installer as Administrator.
I guess I'll ask the guys at Python to update those instructions for persons that use Windows 7 64 bits.
I cannot express in words how grateful I am. I have to travel this Saturday to my daughter First Communion. Now I think I'm going to be able to finish my work, which I was doing painfully by hand. I will be thinking of you next Sunday, whenever I see her smile. Thanks, man.
