Based on your logs you should be around stage 146 or 147. Check your position and see whether the start position of 146 or 147 from the 'Stages' folder is nearer to you. Once you've moved to the same position as shown in the html file you can key in the stage number in the program to continue.
I actually faced the same issue as you, twice! In the end on my third run I manually played it myself at the end. The program doesn't seem to check if you have enough potions for the final bosses so I made sure to manually farm enough spirit potions and battled the boss myself.
