Le-51 bug - no support

i have a serious problem! I can´t play LE on my main steam account for now roughly 3 weeks due to LE-51 bug. I tried many things to fix it on my own but nothing worked. Send about 3 tickets and made a forums post. No communication… it start to annoy me. I love the game and thats why i have bought a second copy on a fresh account. But still i want to play on my main account as well!

Please can you start listening to me and help me…
