I see your problem now. While I should be able to fix this later
(hopefully), there are a few things you should know about cryptoloop:

- There is no guarantee of compatibility across different distributions
or even versions. There have been many reports of breakage after updates
on many distributions. There is no standardization behind cryptoloop and
thus you will eventually be unable to read your encrypted data.
- Nobody likes cryptoloop, the kernel guys want it out of the kernel,
the util-linux-ng guys want it out of losetup.
- You should be able to open cryptoloop volumes with cryptsetup and
dm-crypt instead (cryptsetup create) if you find the right options, this
should be a lot safer than using losetup.
- If you _really_ want to use encryption, you should use cryptsetup and
LUKS, which ensures compatibility to future versions due to
standardization. However, you have to re-create your encrypted volumes,
as the on-disk format is incompatible to the losetup stuff.
