Activating X5 Trial to Full

Hi,

I've installed a month ago X5 Trial version and now I've purchased Full license.

When I try to activate the product it doesn't accept the license number (or serial number

as it says in activation) that came from Corel after purchase.

Then I went to Corel web site and there (in my account) it shows that I have X5 Trial version

and it has an own serial number). But the trial (30 days) is over and I need a working X5 version.

Corel support shows how to activate X4 and the instructions seems similar with X5 but

yet my full license number is not approved.

Does anyone have information on this one?

Thanks!
