Cannot log in or create new account for posting bug

I get a bung in 2.70 and I tried to report a bug but the login screen does not accept me as a username or an email or pwd?
when I try to create a new entry with my username it tells me that it is already existing?
Can somebody help with this?
about the bug: I have a mesh that is originated from vectors that I transformed into meshes. For each sub mesh I want to make the origin to the geometry.
As I have a load of meshes, I wanted to use the Shift Ctrl Alt C from the menus in the tool box bu that did pose the origin away from the mesh. However if I use the object > Transform > Origin to Geometry then the origin goes correctly to the mesh.
If I use directly Shift Ctrl Alt C on the keyboard it gives me the origin out of the mesh

here is the message
