cryptswap - no login possible, repair from cd dosen't work

[Bambam]

Its not possible to login, if I start, theres just a black screen
if I change to STRG+ALT+F1 i can type my login, but it did not work.
I think it's because of the cryptswap1, yesterday I had problems with cryptswap1
Now my hd is secured and I don t know how to save my data
PLEASE HELP!
Thanks a lot,
Bambam
