Well I did a clean install, again. I did install the Hi-Res mod, got the same missing DLL error, but the resolution was applied anyway, and I was now able to start the game without and Janus errors.

Just a quick start of a new campaign, and I still can't see through the periscope. The aperture is very small. There is a red button on the lower right that I can click that appears to put my face up against the periscope but the aperture is still tiny. I uninstalled the Hi-Res fix, still no difference. I doubt any of the extra mods you installed will fix that.

I basically have a vanilla install of PA patched to 1.1.
