If your app is still in the Prepping stage, Salad is probably configuring your machine, downloading miners, and transitioning into the “Chopping” phase. Depending on your particular PC and a few other factors, this can take anywhere from 15 - 90 minutes. So, go AFK and just let Salad do the work!
However, if 90 minutes have passed and you’re still stuck, there might be an issue. First, make sure Salad is whitelisted with your Antivirus program, as this software can block Salad from downloading or connecting to the miners.
If that’s not the issue, you can restart Salad after those 90 minutes have expired (make sure you’ve waited long enough, otherwise you may just be setting yourself back another hour and a half!). Then, submit a support ticket if you continue to get stuck on the “Prepping” stage. We’ll be able to look at your logs and discern whether you’re having Antivirus, internet, or miscellaneous issues.
