Making module manager work

[fairway]

version 1.3.8
no
module manager
cross sell

I installed module manager and it shows up in my admin page but when I click on install modules or new modules nothing show up. I have tried to install the new cross sell which requires module manager and I think that this module manager is not working.
How do I find out ? and if it is not what do I look for to fix the problem?
