Security Warnings Explained

When this application was built 2 years ago I paid $400 and was aided by Junto Media LLC to get a grade A certificate stating this app can be trusted. The certificate expired after a year and I did not pay the money to renew, but aside from being expired the application you download is signed and verifiably safe.
