SS4200-E - all users lost

[idata]

After I add several new users to SS4200-E (1.1.11.32736) and grant them access to shared folders I get very strange users in list (sorry for russian interface, it's users tab):

Now:

- I lose all user accounts (about 20). Only admin account survives;

- I can't delete any "param.c" user;

- I can't add any new user (I can fill form, but user didn't visible in list);

- Shared folders - OK (but lose all permissions).

Please, help me to shoot this trouble!!

Clearly some of the code has become terribly confused, and is reading one of the kernel files as the user name.

I don't think I've ever seen this type of error before, so I'm not sure how to fix it.

Are you using local authentication, or Windows domain authentication?
