Login gives PEAR error

Hi Steve,
I am English but I live in Germany. When programming I normally choose the English versions as they are normally the original versions and don't suffer through translation. (My OS is WIN200 professional German. Eclipse and Xampp is English.) I am saying all this just in case it helps you to solve my problem. I might have more than one problem.
I have a good clean Webauction screen. I click on the Login and I get a frame with the login fields. I feel sure that the first time I clicked on Login all the text was in English. Now it isn't, now the banner text 'Please login ....." is in German.
Login Form stays, username and password is translated.
Submit is now translated into Find. Register is translated OK.
So the first time after clicking login (when I feel sure it was in English) I entered admin and password then clicked submit.
I got the following error.
Fatal error: Cannot use object of type PEAR_Error as array in C:\xampp\htdocs\dataface-0.7.1\Dataface\Serializer.php on line 75
So I repeated the login and this time had the German text where the submit button now says FIND. So I thought oh! I have to click register that was the mistake. Clicked register, and I am logged in as a user.
So I repeat the login and click the submit button (text FIND) and get the same pear_error as above.
My questions:-
#1 Why can't I login what does the error mean?.
and
#2 Is the automatic translation (and sometimes wrong) going to be a problem for me or will it in fact be a bonus? My auction site needs to be in German, Danish, Dutch and English.
Thanks again for all the help.
Best regards,
Tony
