Downloading stopping @ 99%

[anupam_pb]

Whenever i downloada file, it downloads upto 99% & then it stops. If i leave it as such then after 5 min a message appears saying "conection timed out".

I use IDM 6.05 build 3(cracked). My friend(living 6km away) also uses same IDM but there is no problem with his downloads .

What could the problem be ?

Note: There is no such problems while downloading via torrents....
