I don't know if you just misspelled RadsAtom as Radstrom, but if you have the plugin RadsAtom, then do the following:
1. Click the plugins tab on your DemonBuddy client.
2. Highlight RadsAtom by clicking on it.
3. Hit config just to the right of where you just clicked.
4. Highlight the box where it says Death Handling: Next Profile, and type in the number of deaths you want for your character to sustain before it moves onto the next profile.
5. Highlight the box where it says Death Handling: Leave Game, and type in the number of deaths you want for your character to sustain before it leaves the current game and starts a new one.
If you are unable to click on the config button because it is greyed out, then go to your plugins folder in your Demon Buddy folder. Open up the folder that has RadsAtom in it, and make sure that the folder named RadsAtom is located 1 level beneath the plugins folder. The directory should look something like this: C:/Demonbuddy/Plugins/RadsAtom. Obviously you might have a different location for your Demonbuddy folder, but Demonbuddy/Plugins/RadsAtom is generally how it should look for you.
