Reporting a problem with the OpenOffice website

[PowersInc]

My computer was purchased on July 1st from Staples in Bradenton. FL   and 
it came with the pen Office program.  I have used it up until this  week. All 
of a sudden when trying to open something sent to me by e-mail, I get  a 
notice that I do not have Office.
  A box comes up asking me if I want to try a trial program and/or if  I 
already have it, to type in a 25 digit number from my sales receipt. When I  
tried typing that in, it only accepted about 9 of the 25 digits.  HELP>
