Has anyone else lost a saved career?

[Dave Kay]

I've had this game since Day-One and dealt with a few probs before, all solved, but this new one is a total stinker. Did a forum-search and can't find anything like it; while still working thru my first career I began a second later in the war only to lose it completely before I could even return from it's first patrol.

The commander's name is intact and it's saved files are still there (in my Documents) but they don't show up on my second career screen saves--- totally blank! BTW, first career is still functional and no problems.

Using the latest patch 1.4b and my version is only lightly modded, (400M depth gage, realistic depth mod, and a few other 'visuals') but other than that it's nearly "stock."

Anyone else seen this happen?
