Hotfile downloading problem

[strobe]

Hi,
Every time I upgrade to a new version I lose my connection to Hotfile.The same details are listed in the Site rules and the cookie is there in Firefox but it won't download anything except a html file.This happened when I upgraded from 3.0 too 4.0, 4.0 too 5.0 and now with 5.0 too 6.0.I uninstalled 6.0 put 5.0 back on and it working again.Same with Rapidshare.
