Hi, AnnaG. I offered a suggestion in your other thread but am pasting it here too so you can see it. 🙂
Those "Language resource file missing" errors look like minor errors related to language files for the console - like it can't find the language files (the files that translate all the strings into the supported languages). The language files wouldn't impact the performance of the RAID software.
What I'd suggest to try to resolve it is to uninstall the application (it should not uninstall the driver, just the minor apps like the console, etc.) and reinstall it.
I haven't seen the error before so am not sure why it would occur; I'll see if I can find out. Did you install the English version or multi-language version? Did the OS language change after install? Could some of the language files have gone missing?
