[Q] Having trouble with Lollipop OTA topic

So I downloaded the Lollipop OTA update and when trying to install I received the following message.

"We have determined that your phone may be running a modified version of its system software. For your protection, we cannot update your phone. Please revert your phone to the official HTC system software to update your phone....etc."

I am just trying to get stock lollipop and be able to install future OTAs. Any help would be greatly appreciated. Thanks in advance.
