Rich,

I sent you a private email because i want to help fix your problem(which i
feel i can). Please email me back so i can get a hold of you on Thursday,
i will be out of the office on Wednesday. If you reply tonight i could
probably discuss some thing from home, just include your number.
I hate problems, so give me a chance to fix yours(I need a social life 8-)

Simon
