ive done jose once already (got a score of 15 mil, far above the required 10 mil) and it, nor advanced runner activate. what should i do?

title

My pc isn't powerful enough to run this game. it lags on low settings.

The game is great and stuff but i find Jose achievement kinda hard. I spent like 2 hours since i beat the game on hero but cant get it... Any tips/hints/tricks are appreciated. P.s tell me which score potions to use if you mind :) thx in advance

Not sure if it's a bug, but my score is stuck at 5.5mil. I'm ranked Dungeon Master and have all the upgrades bought/unlocked except for the last potion. Do I need to get the next rank to get my score increased? (If so this should probably be explained within the game)...
