To install the ota update first install the original recovery, then relock the boot loader and(optional unroot your phone).
You won't have any problem updating then.
To relock boot loader you can use the guide HTC has made to unlock it or else(easier step) use some tool such as rezo609's all in one tool.
Hitting thanks doesn't hurt
