What version of Blacklist updater are you using? Latest is 1.4.
Here are a couple of screenshots to, hopefully, help out.
Is this the error message you're getting?
You need to make sure you have BIN selected and NOT BOOT.
If this is the problem, try it again and it should work. Also, make sure you unzip the file before loading it.
If you continue to have problems, let us know.
