Minify running in background for hours

Hello, I decided to use the premium hummingbird plugin yesterday and i wanted to minify things in my site to make it run faster. but when i clicked on the minify button last night it said testing site. I woke up this morning and it still says testing site. how long is this process supposed to take? its been over 8 hours. should i try to deactivate and reactivate plugin? or uninstall and reinstall or is it going through so many files it just takes a while?
