Hi Kranthi,
If you are not able to find any log message as recommended by Tobias, then it can be that you are using XP or Vista. Blank screen issue was reported by couple of customers. If you see error as shown below then you are in same boat.
As you said you have got SP01, then you might want to implement note 1890693 which contains the latest Personas XAP file for SP01 with the fix.
Let us know if your problem was solved.
Regards,
Sushant
