Virtuous 2.6 to 2.7 Error

[Krzr93]

Hey I've been using Virtuous 2.6 for many weeks now. Just noticed 2.7 was released and that 3.0 was actually about to come out. Anyways, I downloaded 2.7 from ROM Manager but when I go to install it, it brings me to the Recovery and then fails due to "E:signature verification failed. Installation aborted". Does anyone know why this is happening?

Also should I just factory reset to remove any potential gunk that could build up when updating?

EDIT: Figured out the problem. Something must of corrupted in ClockworkMod Recovery. Just had to reinstall it and now it seems to be working! Feel free to lock.
