Check if your cells are alive or dead (trypan blue stain and haemocytometer).

How long did you leave them before deciding they were not attaching?
Is there someone in the lab who is also growing the cells and they are fine?
Have you had someone show you how to thaw cells properly?
Are you using the medium that these cells have been grown in before freezing?

according to this, http://www.atcc.org/...ate=cellBiology
you seemed to have used the wrong medium. but anyway, sometimes we dont follow exactly the protocol from ATCC. regarding the medium, if a specific one is not available, usually we use DMEM for adherent cells and RPMI for lymphoid or suspension cells. If I were you, i would try DMEM first.
