Hello Frost1349! How 'bout some details for the CTD? Where did you start your career, and with which boat? Where were you, and which boat did you have when you were transferred to Pearl? What boat did you get? What were the dates involved for all of the above? Thanks!
As for LAA, have you double-checked that it is in fact enabled? To do that, open LAA again and load in SH4.exe file. If you're in the "Basic" mode, the little tick box will be checked already. If you are in "Intermediate" or "Advanced" mode, it will say under the "Current" column "True".
2nd to the last, but not least, which folder do you have Silent Hunter installed in, and what are your main computer specs, like cpu, amount of RAM, vid card & OS?
Lastly: "Welcome to SubSim!"
