In version 13.4, using SDK, download when bootloop is used, error is reported:

ERROR:Data2MEM:1-File'\Xilinx\13.4\ISE_DS\EDK\sw\lib\microblaze\mb_bootloop_le.elf' can not be found, or is busy.

There is no problem without bootloop,

The error report is the same as the error that is not connected to the download line. What is going on?

The computer has also been reinstalled, 13.4 has been uninstalled and installed many times, and I have reinstalled the software on the Xilinx Internet and installed it again or not. Only one classmate can use it. Am I the same as her license?

Is there any way to solve it?
