I updated the FDE for the Albatross quite some time ago but I'm not sure Phil every incorporated the updates into the uploaded package.
Try commenting // out the current Contact Points section and replace with these:

BTW, I have enabled reverse thrust. Cntrl+F1 and increase throttle she should back up. To move forward just press Cntrl+F4
Also, you should be able to move from water to land and back without too much of a hop.
Let me know if there are any problems.
