I downloaded the .zip from Direct2Drive and started to install it. Ran out of disk space so thought... fine I would delete the .zip and retry only to find the setup.exe was deleted.
Downloaded again and installed properly.
Then when logging in I see I am getting 7GB more of patch data?
21GB of download quota has just about wiped out what I am allowed to use per month (excess means I get shaped to 64kb/s down from 24Mb/s
Maybe if the patch really needs to be the same size as the original distribution then the initial distribution should be kept up to date. Additionally maybe the setup.exe file shouldn't be deleted if an install fails.
