I reset your activations. You can activate now. I don’t understand what you mean by 24hour mode.
When does DPS crash? Is it happening when you launch the program?
It will help if I can see a Direct x diagnostic report from your computer. Instructions are here http://help.dpsplugin.com/wiki/doku.php?id=generating_a_dxdiag_report
You can email the report to me at email@example.com.
