siemens s7-200

hi
i am using a siemens CPU 226 CN.
when i try to communicate from my PC, it gives me a non-fatal error. for this when i searched the web, i was asked to change the language settings in the software, but i am afraid to change since i dont know chinese language.
what if i am unable to chang back to english?
can anybody help me to solve my problem? why should we change to chinese language setting?
thanks

hi also had the same problem. I had solved it in this way. Open microwin, tools, option, select general, and then select language Chinese. Then restart microwin. But remember the parth how to change the language to English otherwise you will find difficult to understand
