From your video, it seems you got the red AES message about the scenery protection, right ?
This means, either EHAM or AES are not fully updated. The current version of EHAM requires AES 1.96 as minimum, it will not work with any previous release. Conversely, if you have AES 1.96 or newer, it will not work with previous versions of EHAM.
Basically, either you fully update both products, or it will not work.
Also, be sure you put EHAM over the default airport.
And, if you installed anything for that area (NL2000, perhaps ?) be sure EHAM is on top.
