E_ADEPT_REQUEST_EXPIRED_time_settings_non_working

Hello,

I've bought an acsm file from an spanish e-book store and when I want to activate it via Digital Editions the next message comes out "E_ADEPT_REQUEST_EXPIRED". I've checked related discussions in Adobe Community forums and tried the time, time zone, date, and hour preferences but those are ok. I've tried with two different PCs (both OSX 10.6) Also contacted the e-book store and told me to contact Adobe.

Any possible solutions?

Thanks
