The OpenEdge Hive

Hi, just trying to get this to work. So I installed OEA (10.1C), downloaded the zip, unpacked it in my testproject, then went on to step 3 from the installation guide:

3. Modify the dotr/Maia.cls as follows ....

But I cannot find a dotr/Maia.cls. There is a sports.cls that looks like it has the required structure, but should I rename/modify it? And where should it be placed?

I definitely could use a little more help here.
