I know you already seem to have solved the issue, but I'll give a little explanation on how to solve this without having to rely on anything but Blender.
Every vertex is allowed to have only one UV coordinate, this is why you have to split edges along the UV islands like the page you linked explains.
All you have to do to fix this in Blender is the following: Open the UV Editor, got to 'UV -> Seams from islands'.
After this you need to go back to the 3D view with edge select mode active, select one or more edges that are marked as a seam(orange), Go to 'Select -> Select Similar -> Seam'
Finally you simply press the V key to rip the vertices apart at the selected edges.
