@Rithic: If you want we can take a look via teamviewer? send me mail to jiaz@jdownloader.org with ID and PW in next 5-10 mins or let's schedule a session next week?
You can contact us for Teamviewer by support@jdownloader.org next week.
Also you should check if 64bit version crashes with same error,
