What problem are you having? Without knowing specifics, I would recommend deleting your sig.bin from your installation directory and trying to activate again either via the activation dialog or Stardock Central.

Here try this Link

You can activate over email it takes 16+ hrs but its better than nothing

Yes as Ohalland says you need your REAL serial number not the serial number from the manual.

Not the serial number from the manual on the sticker. They may call it a serial number and then ask for a serial number at activation but they dont mean that one!!!!

You have to use that serial number on the website to get your REAL serial number (also called a serial number just to avoid any confusion ) and you use the NEW, REAL serial number to activate the product. Takes seconds really.

So if the number you are trying to use looks like GC2-xxxxx-xxxxx-xxxxx-xxxxx-xxxxx then thats from the manual and its the WRONG one! There are no dashes in the serial number they mean for you to enter. And i dont mean type it in without the dashes!!!! I mean you get a new one that doesnt have any dashes at all.

Make sense?

ok the whole serial number thing has me a bit confused....as I used the number on the back of my manual and it worked when I first installed the game. I own a UK copy, bought it in HMV. activation was no problem teh first time round, so not sure whats happened this time round. Could it be because I have installed it on a new machine? Although I don't know why that would cause a problem as I am using the same account details.
If I uninstall and re install do u think that might help?
again many thanks for the help and suggestions, If Im still having probs i'll email support@stardock.com and hopfully that'll help!
