Authorisation

I am trying to access an ascm file and I'm getting the error message... 

Error getting License. License Server Communication Problem:

E_ACT_NOT_READY

I have tried to erase the computer authorisation but it just says that it is unable to erase authorisation and to try again after some time.  I have cleared my history, uninstalled and reinstalled ADE and changed my password but still nothing.  The file has come from a reputable source so I know it's ok.  I have tried the ADE chat but they simply pointed me here.  I'm aware that others have had this problem, has anyone found a solution?  TIA.
