P Class' Sonar

[Krauter]

hey all, havent posted in a while..

While playing a career in a US P class submarine, i noticed that as i dive to PD, my sonar doesnt work, iv got to manually click depth to 60 feet o be able to hear anything on sonar and see through the periscope (albeit in VERY calm seas).

Any reasons/suggestions on why this is/how to fix it.

Also, one mor eproblem. I had a crash on my computer and SH4 wouldnt work, so i re installed it, however now when i try to load 1.3/1.4, etc i cant. Im also missing some file folders in my computers directory that used to have SH4 data. Because of this I've been playing v1.2.. its so frustrating seeing the big advances here on the forums and seeing how short my version measures up.. how can i fix this installation issue..

(P.S I read the reinstall sticky and didnt undertand anything.. im not much of a computer whizz)
