Dear gtpol,
I appreciate your prompt response,
Three urls you have mentioned are indeed valid, but they are of Filepost. I am not a subscriber to fp and the guest account downloads are restricted to slow at 5 kbps. These files are large size, part 1 is 100 mb, for such size files my internet connectivity works only when speeds are more than 50 kbps.
Alternate file host is requested.
