Trouble with Dreamweaver CS4 activation

Hi,

I have been using a 30day trial downloaded from the DW Adobe page. The trial
expired whilst my purchased DW CS4 was in transit. Today it arrived and I
installed it, however when I am prompted to enter my serial number, found on
the back of the DVD, it tells me the serial number I am entering is not valid.
Ive tried time and time again, and checked the digits thoroughly.

Can anyone kindly advise me? Could there be a conflict because I installed the
new version without uninstalling the trial previously? I am at my wits end.

Thank you.

OK, after some blood sweat and tears and exhaustive hunting through the adobe
site, I found the solution.

If anyone else finds themself in the same predicament, the problem is likely
to be caused by the language options you choose when installing the product.

All A-ok now.
