Hi there,
If you believe there are other files installed in your system that might be conflicting with your games, you can try using CCleaner to clear out issues and errors.
While we suggest using CCleaner, EA does not provide user support for this program–use it at your own risk. Please follow any installation guides straight from CCleaner when installing and performing program set-up. You can find help on CCleaner’s support page.
EA does not benefit in any way, monetarily or otherwise, from the promotion of this program.
