IDM problem

Hi

I'm trying to download a 900MB executable file using IDM 5.17. It has almost downloaded (99.99%), only few bytes are left. But i cannot get to download those few bytes in order to complete the download. IDM reads 'Receiving data..' though the Transfer rate remains at 0, and Time left is tagged 'unknown' (resume capability is tagged 'Yes'). I kept it that way a pretty long time though download doesn't seems to complete. Anyone else has encountered this problem? If i cannot download those few bytes, those 5-6 hours of downloading will become totally useless. Please help!

Thanks.
