Hello Again!
Okay, I downloaded the file and installed it. It is definitely your regional settings. Eventhough you may have EN on your taskbar, please do the following, and then start PC-Doctor.
1. Choose Start
2. Choose Control Panel
3. In Classic View choose "Regional and Language Options"
Or in Category View choose "Date, Time, Language, and Regional Options", then "choose Regional and Language Options"
4. Choose Regional Options Tab
5. Under the section that says Standards and formats" click on the drop down box and choose English (United States). Under location, you can have any location you would like, as the "Standards and formats" section is what controls the language settings of PC-Doctor.
6. Now start PC-Doctor. (You will have to restart PC-Doctor for the settings to take place, it will not happen on the fly.)
Let me know if that fixes it. It should. And if it does work, please come back and visit and bring your friends too!
