You got 2 GB memory, 2 CPUs, and 50 GB storage for $21.60 for 6 months. 2 GB memory, 4 CPUs and 50 GB storage is $24.30. The difference is $2.70. Go to https://www.paypal.com/cgi-bin/webscr?cmd=_s-xclick&hosted_button_id=P63828V7WFM54 And make a payment for $2.70. Let me know by posting in this thread when that is done. In order to upgrade your CPUs I will need to shutdown your VPS for 10 minutes or so, and then power it back on after the upgrade.
