When the child program is opened in Olly the second Olly go to View->Threads and make sure they are not suspended.

If they are suspended then its a fault of Olly and that is your problem.
Olly has a bug that you can only attach once per session. That means if you opened Olly #2 and attached to something, anything else you try to attach to after that will have suspended threads.
The only way to fix it is to open a fresh session of Olly and attach to the child process.

That may or may not be your problem.
