S3 browser says my account is not valid

I created an amazon s3 account and I downloaded s3 browser for
windows here:

I put my keys in and tried to create a bucket, but it said my s3
account is not valid … Is it possible it is too new ?
Is there a better free browser ?

Thanks

I tried the ruby aws gem. If I can get a key and secret key from
amazon, I would assume my account is valid ? - unless it has not
refreshed through the system.
I get the error below.

I assume the "+’ and “/i” at the beggining and end of the secret key
are part of the key ?

If I can use this gem and get it to work, then maybe I don’t need an
s3 browser ?
