You can choose either one of the following solutions:

1) Move the file Classes.m out of the directory ProgrammingInMathematica 
   and put it into the parent directory 
WolframResearch\Mathematica\5.2\AddOns\ExtraPackages\Classes.m, then 
evaluate Needs["Classes`"]

2) Keep the package Classes.m in the directory ProgrammingInMathematica 
  and evaluates Needs["ProgrammingInMathematica`Classes`"] (you can 
disregard the warning message).

You can check that Classes is correctly loaded by evaluating

$Packages

Out[2]=
{Classes`,Global`,System`}

and start using it.

In[3]:=
?Class

Class[class, superclass, variables, methods] defines a new class as a \
subclass of superclass. Class[object] gives the class of an object.
