Unable to download Blloc ratio files on desktop

I have been trying to install Blloc Ratio from Desktop but while downloading the file it freezes at a certain point and then the download halts and does not proceed further. I have tried downloading a lot of times but the same problem occurs again and again. I also uninstalled and then re-installed the application and tried downloading again but the same problem occurs. I even have repeated this procedure for 3-4 times now. Please tell me what to do.
