Problem with changing Language

Hi all,

I am having a problem with the language of the error messages that I get in case of any problems with tables in the dictionary. The error message and the codes are displayed in German.

Please let me know how can I change this to English.

Another issue while referencing a SAP provided domain is that it asks to change the original language to original language.(original language: German, Login language : English).

Please help with this.
