I just downloaded both files , and there are all working fine with my computer.
I have no ideas what kind of error you had (you did not said it).
Please check out the file size:
ejs_users_ntnu_fkh_micrometer2.jar: 1359511
ejs_users_ntnu_fkh_caliper.jar:1337066
You need to download it again if the file size are not the same as above.
You will need to at least close your browser , otherwise you might get the cached file.
If your network provider keep a cache, you will need to download it from other computer/network.

If the file size are O.K. Try to check out java console and find out what are the error shown.

If you can provide more information, may be I can try to help you.
But there is no way I can help if you just said you have problem or you got an error without further information.
