Error when uploading for a while ?

[starcow]

Hi!!!
      Before going to bed every night, I used to upload 2gb data to Megaupload Premium account. However, next day Fileuploader show me a message that are Critical error, system error Code:87 ,and EOSError. Then I open the "FileUploader.err" that indicate as following.
     
2011.02.06 22:10:28 Error #11

 Could you help me to fix this problems?  Thanks a lot.

P.S.
My operation system is WIN7 x64, and install Ramdisk(Superspeed).
There is no antivirus program in my system
