Deleted a .dmg file with password. Recovered with Data resuce 2 but wont work.

Hi!

I will try to tell you what happend.

I had a very important file witch I had a password on. A .dmg file with password made in disk utility.

Then i did manage to delete it from my Mac. I used Data Rescue 2 and
got the .dmg file back.. But it had changed the name to D-00005.dmg istead of Private.dmg ( can not remember exactly what the file was named first )

The number one reason I know this must be the file is that it was 100mb.
I only made one file with dmg file with 100mb. I remember the password, but it never ask for it when i try to open it. I`ll just get a message that it cant be open.

Please help with this one !

If someone has a answere for me that can help me get what is in that .dmg file back I will transfer 50 usd on your fulltilt poker account.

Kind regards

It says that it can not recognize the file. Is there nothing i can do?
