Large downloads

I was downloading a trial graghics suite from corel. It is about 190 MB. During this after about 75 % download was through, a message that the connection with server was reset the download cannot be completed. On starting the download again it starts from beginning. In my previous downloads sometimes the download re starts from the point it was interruptede. Is there a setting in the os that has to be checked. My OS is Windows XP. Please help! Starting the download from scratch with no surety that it would complete,makes me write for help.
