chrome not showing previous profiles, tabs and windows anymore after crash

I'm using 14 different profiles in Chrome Portable, each profile has a few windows and several tabs.
Setting "continu were you left off" is on .
I had to hard reset my pc and now when I start Chrome portable, only my main default profile starts without the tabs and windows that should be there. Worse when I try to open another profile from the "other people" list none are there anymore.
"last sessions" and "last tabs" files are still available, all but one "current session" and "current tabs" are still there as well, those two files are missing in the "Default" profile folder but I renamed "last sessions" and "last tabs" to "current session" and "current tabs" in that folder as am I supposed to do in such a case. All profile folders are still available too including their full directory structure, so Default, Profile1, Profile2, etc.
All that data seems completely ignored now.
How can I get all profiles to load again and get my history, tabs and windows back per profile?
Can I manually force chrome to load the profiles again somehow which are still there after all?

Thanks very much in advance for any possible help. I really need this fixed asap. Much appreciated.
