Was in IT many years ago, then went into management and have become useless.  Have seen ColdFusion in action and would love to play with it.  Learn-in-a-week is starting to accumulate non-productive days.

ColdFusion 11 installed, MySQL 5.7 installed - all running, Sample files down and verified, Port 3306 seems OK , created database from Command line.  When using CF Administrator  get the message that connection to database server could not be created.

Any help from the community would be gratefully received
