Problems with loading (google drive)

I coded an experiment with a total of 78 audio stimuli. They are stored in google drive and only linked to psytoolkit. Whenever I try to run the experiment, it stops at 34% and doesn't continue loading. I tried with several browsers, but it won't work. My internet connection is good, so this also can't be the problem. In another experiment, I had three times the amount of audio stimuli and it worked just fine (they were stored in dropbox tho, because of full storage I had to switch to google drive). Does anyone else have those problems and knows how to fix them?
