I thought "upgrading" to the "Pro" version would help...I was VERY wrong.

Every single time without fail I connect, start downloading files, within a minute or so my entire computer locks up, and I loose my internet connection. Why is this consistently happening?? As I said I upgraded to “Pro” because this was happening with the “free” version. Anyone else have this problem? What have you done to fix it?

Thanks for the help.
