So about one-two months ago i deinstalled plays.tv, cuz i was short on free space on my hdd(i solved the problem). So yesterday i reinstalled both plays.tv and raptr, and it didn't record my league of legend games, plays.tv says that it records the game(shows the message in upper left corner of the screen), but after game is done there is nothing in both plays.tv client and the folder which it saved the files.
Typically if it says it's recording, but doesn't create a file, it's usually because something interfered with the encoding process. This usually it another recorder running, or some kind of other program that hooks into the game. Have you made a support ticket about this issue?
