"Engine Error. Could not load library client. Try restarting. If that doesn't work, verify the cache."
This is the error I receive when I open AArcade. I mentioned this to you before, and you said restart the computer. Did that, didn't work. I restart Steam, same thing. Also every time I open Steam or try start AArcade, it does an update before starting. Sometimes its 2, 3 seconds, sometimes a minute. I've tried several times and the same thing happens.
I also tried reinstalling it like you said by backing up my files, I havent even put my files back in and it won't work. Last time I was on was in Flynns arcade the other night. It worked perfectly then. I havent done anything to the game or workshop until today.
Could be the latest update or something, or maybe my Steam is broken. I have no clue. I can't even open it to get an error log

also, when I verify the cache, it verifies alright.

its clearly either a problem with either Steam or AArcade because I've just reinstalled it and still the same problem

Hmm, I haven't seen this one yet. I'll be pushing a client update before Wednesday and hopefully this resolves your issues. If not, I'll be more than happy to troubleshoot with you guys on this issue after the Wednesday update.
