Plutonium

so i downloaded plutonium yesterday after not playing on it for i dunno a year or two, played some MW# all night, then today got b02, played a few hours no issues, went into some private match killing bots while waiting for a friend to finish making ceaser salad, hit a horrible trickshot on a bot, immediately after the kill cam ended my game crashed, i reopen plutonium, it prompts me to log in, and i recieve a notification that im banned for 7 days. this pc was recently factory reset, i have plutonium one other game, and eqqualizer APO installed. what possibly couldve got me banned? im so confused
