Last time Ignition did an update that broke DriveHUD it took them a little while to get it fixed. Don’t worry, I am sure they’re trying their best to rectify the problem. Trust me, I would prefer them trying to fix the problem then to be answering 100 different questions all related to the same subject. Be patient, everything will be fine.
Also, you can still import your hands into drive hud, just you have to wait for the delay that Ignition sets on when you can access your hand history/game transactions, so your stats are still calculated, just not in “real time”.
