POSTAL 2 version 5000 Hotfix 1 has been released, which should solve the most common crash users are experiencing in Windows 10.

Here's a list of fixes in this version:

• Addressed a crash (LockRect failed: D3DERR_DEVICELOST) that could occur when attempting to run in fullscreen mode on Windows 10 or under certain other machine configurations.
• Fixed the “Pussy on a Pedestal” achievement not activating (again)
• Added the ability to unlock the “RAFIBOMB” achievement in POSTAL 2.
• (POSTAL 2) Streamlined the final cutscene and boss fight in the ******** Interactive office.
• (Paradise Lost) Fixed some minor display problems with a hidden weapon.
• (Paradise Lost) Fixed a hole in the Meadow where the player could fall below the map.
• (Paradise Lost) Fixed a bug in the Animal Control Center where the doorway to the dog kennels could be blocked on subsequent days after the related errand.
• (Paradise Lost) Fixed some ungrabbable pickups.

We have other fixes in the works that didn't make it into this patch, including fixes for settings in the hidden menu, so stay tuned for those.
