Torp room out of gas?

[Seaveins]

OK. I am a newbie and had some problems with my crew loosing their voices. I took veteran advice and uninstalled everything and reinstalled SHIII, patch 1.4, and TGW's 1.1. I started a new career in the 1st flotilla, 1939, Type IIB boat. I found a target on my first patrol, sunk it, but my crew couldn't reload my reserve torps. Just flailed around at about 30% efficiency with both tubes' status reading "Torpedo waiting in queue". I beamed back to base, replaced an officer with a torpedo qualification, assigned a warrant officer with another torpedo qualification, and went back out to sea. Guess what? I found a medium merchant, hit it with torps 3 times, didn't sink it after 3 hours of watching it list (game is saved at that point), and my crew still can't reload! One officer w/ torpedo qualification, two warrant officers with the same, 7 other warrants and two sailors and I still get "Torpedo loading waiting in queue" for all three tubes hours later. What am I doing wrong? Is it time to attach the plank?
