Problem with the Validation

Dear Team,

I'll ask you for help because I've some problems to validate my new edited htm(l) files. Sending a local file from my harddisk for validation I'll get the message that it is only plain text. Sending the same file for validation by URL from my internet provider the check will be done without any problem.

Testing your service with older files by file upload now I get the message too, that all are plain text. But all the time before I used your service without any problem by the file upload and the validation was done The only change I've made was the upgrade installation of Windows XP home to the new version SR2. Do you know if the XP-SR2 is the reason for the error message? Do you have any advice to solve this problem? I think it's better to validate the new html-files before sending them to the server.

I'll hope for an answer, please use my email address: d.mietke@arcor.de
Yours faithfully
D. Mietke
