E-TDS validation utility upload file error

Good day everyone,
On my new computer I have installed Windows XP Professional.
A few days ago I start using e-TDS program for accounting and tax.
When I try to Validate the file I got an error message.
I don't know why I got this error. Any suggestions?
Thanks,
Jeremiah
