Well, i will try to giv a solution, but dnt knw if that will work or knw, i think it shud.. so here it goes...
SInce u hv installed µTorrent, u shud hv that same torrent file (in sum kb's) from ur cousin, now do the following:
1.) Place all the contents (that u hv 80 completed) in a folder where ever u want it..
2.) Double click on the torrent file (again on ur PC) using µTORRENT, it will ask u where to d/load files (as this is the 1st time u are using this file on ur PC).
3.) Jus navigate the torrent (for saving the files) to the folder where u earlier stored that 80% of the contents.
4.) the µTORRENT application will start checking the files (in percentages), and will continue from the 80%mark..
Try i adn reply here..
