This question is an exact duplicate of:
I purchased "Reputation to the Max" and increased my reputation by 10x.
And like a good SE citizen, I immediately went to the review queues to do my part (for the day).
However, the review queues indicate that I don't have enough precious repz in order to perform any of the much needed reviews.
I believe this must be some sort of bug within purchasing the "Reputation to the Max" power and ought to be resolved.
