I had a very similar problem. Those modules you are having trouble with are either unstable or in development.
Not being a programmer, I choose to use only stable / standard modules. If you want to do the same, your problem can be fixed by
- logon as administrator
- go to Admin -> Modules
- Delete the unstable / in development modules
- follow the directions Moodle gives you in the process
It worked for me...just need patience while Martin and team work the bugs out of those newer modules.
