Steam Achievement Manager 5.1 (SAM 51) is now avalable and fixes all the Vista related crashes/bugs. You can now unlock the Huntsman, Dead Ringer, Cloak and Dagger again using this. Works with TF2, Left4Dead (L4D), and a bunch of other steam games like FLOCK!, Light of Altair, Plants vs. Zombies and pretty much any other Steam game.

Instructions
- Install Microsoft .NET Framework 3.5 if you do not already have it installed.
- Download Steam Achievement Manager 5.1.
- Extract it to a directory that is convenient to you, but not your Steam directory. It’s a ZIP file, if you don’t know how to extract a ZIP file then you probably shouldn’t be trying to use this tool.
- Run Steam if it is not already running.
- Exit any active VAC protected games if any are running. While this tool does not directly interact with any game itself, it is better safe than sorry.
- Run SAM.Picker.exe and do whatever you want in it.
I’ve noticed that Trine is not yet available for the Achievement Unlocker. Would it be possible to get it?
DO NOT USE THIS
I just tried it and it didnt work, kept crashing. But 15 minutes later my steam account was compromised. Bit fishy don’t you think? An account i’ve had for 5 years is suddently hijacked 15 minutes after running this programme?
Well, everyone’s entitled to their opinion. What ELSE did you download and run, along with the SAM? Perhaps an aim bot? You said it kept crashing, did you remember to download .NET framework 3.5? It won’t work unless you downloaded and installed .NET 3.5 from microsoft’s site. Are you using windows 7RC or something? Did you exit TF2 first? You’re the only person to download it and EVER claim it was a hijacking program. Did you click on a link from someone you didn’t know?
worked perfect! Thanks:)
