Corrigido erro na busca manual

Depois de mudar essa linha, o erro sumiu para mim, porém agora sobrou o seguinte erro:

 - NOTE: IGNORING THIS CAN LEAD TO MEMORY LEAKS!

Outra coisa, o regex3 do arquivo LegendasTV.py talvez precise de um escape no final
regex_3 = "<button class="icon_arrow" onclick="window.open('([^\']*?)', '_self')">DOWNLOAD"

Nesse caso, no </button>´ do final, devendo ser </button>`
