Ok, lets start with the advice for this situation from 
the FAQ: First, calm down.

Some questions:

1.What exactly did you do? 

2. Did you install squeeze 64bit over some other installation 
   you had before? What kind of other installation was that?

3. What was encrypted before and how? You seems to think sda5 was
   encrypted with LUKS, why do you think that? (What do you
   know about it that tells you it was encrypted?) 

4. Was sda1 encrypted before and is it still, or does it now 
   have a new, unencrypted squeeze 64bit installation on it?

4. Did you create/manipulate any partitions or file-systems?
