I've always used LolReplay for Replay content and I gather a lot of footage to record and edit for later when I have downtime, like when I'm on the move or have no access to internet. I've been struggling to even get some to play. Only way I can review Replays is through the actual client so I'm inclined to think it's something to do with LolReplay. There's no popup, no indication of what it can be. It gives me the typical "League of Legends" opening but then it'll be stuck on a black screen and the mouse will be loading. If I tab away, it'll turn transparent but the mouse will remain a loading wheel. I even tried to upload the game of choice to share but even the url for the replay doesn't work.
