Default Whats app problem in desire vc

Hi everyone I m new to xda and I just joined it
I am using HTC desire vc I got problem in whats app it closes without any error and it starts only when I clear my data of whats app from system and in this process I also looses my unread massages. I have been told by whats app support that problem is due to hindi language. I am also not restoring my back up. Still this problem come every couple of days. Is anyone got solution then please let me know because sometime I looses my important massages also
Thank you in advance
