Apparently the error lies in the commands.cfg file:
"OK, go to my FileFront and download SetKeys. Then, go to Program Files/Ubisoft/Silent Hunter IV Wolves of the Pacifc/Data/Cfg, and find the Commands Cfg file. Copy it to another location and rename it to Commands_en(as in the same file SH3 Uses which SetKeys seems to only recognize), and find Order_Maintain_Depth, and change it to Maintain_Current_Depth. Once you are done, rename it Commands again like the stock SH4 called it."

My apologies if this has already been posted. I just got in from a long day at work today.
