Upon further examination it seems the files are dead, I've checked my 
backups and the only one that still works is much older. I've taken the 
files appart and found that SHA1-1k is used to make a hash from the password 
which is then used to verify the password, but that's no good now as it's 
obvious that the files are damaged and that might be why OO.o thinks the 
password isn't any good. This is not isolated to one file, other 
OpenDocument files from OO.o 2 beta are so badly damaged that even ones 
without password protection won't open, I don't know what is wrong
with OO.obut the version 2 beta seems hacking up it's own spreadsheet
files (happened
three times so far, not too common, but annoying and potentially 
disasterous).

I hate to use MS Office because it's not friendly with any other office 
suite, so I might very well have to dig up my Java books and write a program 
to do what I had the spreadsheets for. Personally I'm no fan of Java, but I 
lost all use of Qt after version 4 was released and I was left trying to 
learn it all over again.
