What year/model/vehicle...?

Can you paste the text here from the log window...?

Also, what software and firmware versions are you running?

could not paste the error,but here it is word for word.

Error
Bootloader rejected.
Reason:
EFILive could not unlock the PCM.
Make sure you have selected the correct controller type at the top of the window.
Check the "Try Alt Keys" checkbox to try alternate keys that may unlock this controller.
If the PCM is locked and you know the unlock key,please enter it.
If this PCM was locked by Flashscan then you MUST unlock
the PCM using the SAME Flashscan interface that was used to lock it.

i am using the same interface.
also firmware version is 2.07.04

Couple of things to do please:
1) Upgrade the software and firmware to the latest pre-release version here: http://forum.efilive.com/showthread....se-candidate-1

See these knowledgebase articles for more details on the process:
- Software
- Firmware

2) If after updating you are still having problem please see this knowledge base article and provide just the one debug/trace file.

Cheers,
