I dont know if it will help but.. My version of SDIO was in russian and still is..
(SDIO Seems to start out in russian when downloaded for me, maybe it is for you?)
I cant read/speak russian but i dont use the app normally, only through cmd/bat.
When testing the app.. All i did was click language on the left side and clicked English.
(You can also use a custom config file with english language set as default)
