increase time is nothing... they reset router, change IP and get download

sorry but sales do not depend on this... the opposite. sales will increase when FREE users see that they have to download a small file instead of getting directly the file... they will need to upgrade if they do not like this.
FileMates is a business. Not an organization. 90% of free files is just too much. All other networks have ads and pay per install programs like the one FileMates will use... FileMates can not conitnue FREE for FREE users...
I say once more, the installation for the toolbar is not obligatory. The user will choose to install it or not.
Premium users will not need to download this file. Free users will see a message saying that upgrading to Premium they will get the DIRECT file link and they will not need to download the exe file first

This will increase sales apart from installations income...
About mirror, every free user that knows about mirrors already searches for mirrors as the speeds we offer to free users are low...
Sorry but the decision is taken. I am only waiting the economical proposal. If it is good consider it done. AT least the testing period to see results. I searched the market and many good websites and very big ones use such programs.
