I get this error: Depot download failed : Manifest not available

Anyone know if im doing it wrong or how to fix it?

Adam probably deleted the patches. I cannot upload them but i have the most used. Its piracy. I have to ask Insym because he is moderator of that so we will be able to know what to do from now on.

No, Steam disabled downloading Patches in January 2020, I downloaded a few yesterday using this guide to get around it: "If you get the "Manifest not available" error, do this and try again:

1. Run Cheat Engine.
2. File -> Open Process -> Steam
3. Set the right-hand settings to the following:

• "Memory Scan Options": steamclient.dll (just keep pressing S when the drop-down is open to iterate through each and find it quicker)
• "Value Type": Array of byte
• "Hex": checked
• "Writable": unchecked (!)
• "Array of byte": D0 84 C0 0F 85 2E FF FF FF

4. Click "First Scan". You should get a single Address and the searched Value next to it.
5. Right-click the Value -> Change value of selected address(es)
6. Enter new value: D0 84 C0 E9 2F FF FF FF 90
7. Click OK. Done. You can now exit Cheat Engine and are able to downgrade games without the "Manifest not available" error, until you exit Steam. Continue through the guide as before.

Once all of that is done, if you can't find it, go through System C: - Program Files 86X - Steam - Steamapps - Content. The folder "appxxxxxxx" will contain the game."
