I'm somewhat new to Eagle and I'm trying to design my first board using 7.5.0. and the autorouter is acting up. The first time I ran the autorouter on my board, I was able to set the multithread feature to use all 8 cores and on high effort settings, it came up with 22 variants. Although it took a while, it came up with a couple promising results. after selecting one by mistake, I couldn't figure out how to reselect a different result so i decided to just use the ripup command and delete all the other ones out of the folder containing my files to start fresh. I've since figured out how reslect different variants, however I'm having trouble making the autorouter run correctly again. I want it to run again with the option of 22 variants, however it isn't allowing me to do so. With all 8 cores selected and on low medium or high effert setting, its only giving me the options of toprouter and 3 variants. Not sure whats going on and any help would be appreciated.
