Yes the key should work fine. I personally have ta.keys which look exactly the 
same.

Thanks for your answer. Where can I find config and log files to post it here?

CHeck if your log says using ta.key as static key file or "Control Channel 
Authentication: using '%s' as a free-form passphrase file" to be sure that 
openvpn reads your file.

The copying the log see the FAQ

Not as a free-form passphrase file:

From the log it looks good. Try to import then windows configuration.

Wow, imported configuration worked. I then changed keys from "inlined" to 
android store and path to ta..key and it works now too.  I do not get it, but I 
do not care :-)

Thanks, Michal
