Sql Server CE 3.1 corruption

I have a quite important sdf file, which is corrupted. If I try to open it (password protected, 24 MB) I get the 25017 Error, this is well known and I was be able to fix this Error 开发者_Python百科in the past with engine.repair but if i try this, i got a complete System error (not catchable).

Ausnahmecode 0xc0000005 Ausnahmeadresse: 0x017b65d4 Lesen 0x00000064

The same error occurs if i perform engine.verify or engine.compact I've tryed to download some desktop sdf viewer, but the all crashed too.

Dit anyone have any idea what's the problem and how to solve? Or am I able to decrypt my databasefile by myself and read the informations with a Text Editor?

Have you tried installing build 8083 or later, and then run Verify/Repair http://erikej.blogspot.com/2010/08/sql-server-compact-35-sp2-downloadable.html
