This is what you need to do if you ever get this error.
It's a total pain in the ass and i found out the hard way. Figured i'd put it up in here where it'll be for all time.

Question Why do I get an error message Patch Failed, or Unmodified Content when I try to play after installing the 1.10 patch?
http://support.ea.com/rnt/rnw/img/trnsp.gif Answer These errors can be caused by a software conflict while patching, internet connection issues, or a corruption in the software files. To make sure you have a clean installation of the game please perform the following steps:

Manually uninstall the game. (http://support.ea.com/cgi-bin/ea.cfg/php/enduser/std_adp.php?p_faqid=14051)
Use your Spyware removal tools to remove any malware and adware from your machine.
Perform a Disk Cleanup, Scandisk, and Defragmentation on your hard drives. (http://support.ea.com/cgi-bin/ea.cfg/php/enduser/std_adp.php?p_faqid=10719)
End all background tasks to prevent conflicts with other programs. (http://support.ea.com/cgi-bin/ea.cfg/php/enduser/olh_adp.php?p_faqid=10700&p_created=1124383132&p_sid=<? echo 5Yl5Dmki ? >)
Empty your Temp folder to prevent file conflicts. (http://support.ea.com/cgi-bin/ea.cfg/php/enduser/olh_adp.php?p_faqid=10705&p_created=1124387056&p_sid=<? echo 5Yl5Dmki ? >)
Install Battlefield 2142.
Download 1.10 from a reliable mirror site. For example, the best mirror site for the US would be the Battlefield 2142 main site or the EA FTP server.
Here is the Battlefield 2142 main site. (http://battlefield.ea.com/battlefield/bf/)
The EA FTP can be found here. (http://largedownloads.ea.com/pub/patches/BF2142/1.10/)
Ensure that the patch size is the correct size. The 1.10 patch should be 32.7MB when downloaded correctly.
Make sure that you have at least 3 gigabytes of free space on the drive before attempting to install the patch.
Install the 1.10 patch.

Note: Make sure that you only install the 1.10 patch. Do not install any third party software, mods, or any other updates other than the 1.10 patch.
Once the patch has completed installation try the software again.
