Digital Editions does not install on IBM ThinkPad R50e

[aeletr]

I am installing Digital Editions on 2 computers : one Dell PowerEdge 1300 and one IBM ThoinkPad R50e,  both running Win2000 SP4. Installation with computer authorized goes fine on the Dell but in the IBM gives error
"E_ADEPT_REQUEST_EXPIRED http://adeactivate.adobe.com/adept/Activate 2012-09-13T04:40:34-07:00%20(1347536434000)%20is%20before%202012-09-13T05:10:33-07:00
%20(1347538233975)"
in both cases whee I as to authorize the computer or not. This computer is running fine all sorts of large software from a lot of vendors.
Any hint ?
