Imran,
I already installed the rollup 3, it did not solve the problem. But i did manage to fix the issue!
if you encounter the same behaviour, take a look at your temp folder, probably located at:
C:\Documents and Settings\Network Service\Local Settings\Temp.
Access this path from a Run command, and check the number of files. If it has 65,536 temp files in the folder, than the max has been reached.
Delete the temp files from this folder and run the bulk imports again.
