Do you have access to another computer, even if it's at a friends house.
And try and use a LAN connection, not wireless, wireless has way more potential to drop out and such.
Bottom line is use the best, steady connection you have.
You should always copy the downloaded files to a back up drive.
Also I think it's super cheap for you to upgrade to X3.
X1 was full of bugs and X3 is the best version.
