Error -activation

Dear All,

I've installed Adode Digital Edition 03 (ADE03) and tried to read a 'URLink-1.acsm'file. The ADE 03 didn't recognise the acsm file automatically.I dragged it the acsm file and placed it on the ADE03 icon; it then opened and flagged 'error - activation.'

Somebody help me to resolve the above issue, please.

Many thanks,

Daniel
