Reactivation for DS V1R3x64

how can  reactivate the DS V1R3x64  in standalone mode .I read  the ''Free Version Installation and Upgrade Guide'','' Activation and Licensing Models_V06'' ,''Clean Reinstallation '' and a lot of thingns  here ,i reinstall  20 times or more the DS64 but it was not possible to operate as standalone .The pop-up message was always ''reactivate the product to use it ''.

the only way to work without pop-up message, is to change the date of win7pc,with previous date .

pls advice  .
