Finally, I found the problem with new uploader why can't upload files to Hotfile.com
I downloaded the new uploader again with my NOD32 closed and I closed it forever.
Then I tested to upload files to HF via the free version of new uploader, works fine.
After that, I insert my registration key and the uploader for uploading to HF not work...
with the error:
2009-8-30 2:53:04 UP: FID (EIdURIException:Protocol field is empty) (hotfile.com)
So, I think maybe the registration broked the app
