I am at attorney in Floride and am the proud owner of adobe acrobat 7 standard (necessary in Florida to file legal papers with the courts).  My computer went belly up and I am attempting to restore it to its prior state.  I cannot get it to activate my product.  I realize you have quit supporting acrobat 7, however, I need it.  How do I get it activated.  I have tried by web and phone (which says you have quit the phone activation).  how do I get it activated.  I have downloaded the CS2 product from creative cloud to no avail.  What do I do?  Ida Roberts
