A DCT error means the map is not activating so you need to check if there is a meta code released for the map (which should've been done before downloading it in the first place). Secondly, you cannot create a *.DCT file yourself...so don't even bother trying.
Europe_West 1035.9676 = yes, can be activated
Iberia__1035_9697 = no, can't be activated
The meta file you're looking at inside the map should not be opened or modified in any way otherwise you'll actually be creating the error yourself.
I would recommend starting again and downloading FastActivate from
[Please Register or Login to download file] and look at the enclosed MyMeta.txt to find new 1050 series maps that will suit your needs &
already has a meta code published. Download your chosen map(s) and extract them to the root of your device...and also extract the FastActivate archive there too. After that run FastActivate from the root and select option 2 to activate the map(s).
