Valery, I have one idea. It's not related to assemblies, but to Era VFS only. Win 10 functions are bridges to another functions. I intercept bridge, but not the functions themselves.
Unfortunately, I don't have Era sources prior to 2.6 in repository to fix those VFS issues, thus I just cannot recompile it. But even then I won't be able to maintain fixes for further updates.

Please, try at least clean ERA 3.8 assembly without external mods and with old SSS mod. If it works, then ok. If not, I'll see what can be done with old code but give no promises.
