Another post about a bug in leaverbuster lowerpriority queue

I am not going to flame the riot staff here and am not going to say anything rude. I just would like to know why I can't find a match after waiting for 2.5 hours. My timer keeps resetting, whereas in the past it has taken the full 10 minutes then put me into the regular queue. Please help, I shouldn't be having anymore problems with leaver buster for the time being because I got my computer fixed. Thanks!
