the present trainer HEART OF THE SWARM TRAINER 2.0.6.25180 is no longer useable. the sawrm and liberty have been updated to 20.7.25293. if you attempt to use the old trainer online, it will draw an error that will lock you off for an undetermined amount of time (mininum 30 days}. play offline and wait for the update
The game crashed on me when I tried to use the latest trainer, just err to desktop. Expected with the patch that came out today. Thankfully it did not block me. Were you trying to join a game against players or ai henry?
