Waves afterServerrestart not accessable anymore

I loose all data after every restart of the server (Alt+F4 in the commandline or server restart, maybe I have to exit differntly?), I can still see the waves in the list, but when I click on them the programm crashes and I get the following error (1), the only thing I can do afterwards is click refresh but its the same every time; to me it looks like the deltas are not saved correctly to the hdd, even though I can see them in the folder, maybe they can't be associated correctly with the links in the list? anyways the config settings can be found here (2)
