won't take password when installing

Clicked on downloaded Flash Player update and it prompts me to enter my password for Adobe.  I did and it would not take it.  I went to my Adobe account, reset my password and tried again.  It still won't take my password.  Any ideas to fix this?  Also, could I delete my adobe account and start again?  Can't figure out on their website how to do this.  Thx.  Jan
