Download the correct 1.41 BETA Update
If you don't you will see an old version of the code where I wasn't quite done with the new pitcher usage AI -- closers will get about 125 appearances a season

Also, it looks like I forgot to update the text in the readme file to mention that it was 1.41 (in both the original update and the "fixed" version.
Lastly, this stuff is contained in the readme but I forgot to mention it in my post:
(Additional 1.41 release notes below)
- Installation: PureSim now installs the latest version of the Microsoft .NET Framework (2.0) (You will only see this install if your machine does not already have the Framework. Most people already do, since it is pushed out via Windows Update.) PureSim simply runs Microsoft's official installer to install the framework.
- New: Finalized official support for loading add-ins and expansion packs created using the .NET Framework 2.0 (For example using the freely available Microsoft Visual Basic Express 2005 and Microsoft Visual C# 2005. More updated info coming for modders/developers soon! NOTE: PureSim supports creating add-ins in VB6 and .NET 2.0. .NET 1.x is NOT a supported platform.
- Update: Re-integrated PureSim's add-in download feature with the PureSim server. Expect us to release add-ins and expansion packs over the next few months that you can download and install from directly within the game.
* If you are a skilled developer (VB6/NET/SQL/DHTML) and would be interested in creating add-ins and expansion packs for PureSim, I am currently evaluating a number of options, with one being the ability to add your mods to the public server so folks can discover and download them from within the game. Please send an email to shaun@puresim.com if you are a developer that would be interested in this program, which will also give you access to some additional samples and SDK updates.
There is a ton of undocumented stuff, but it's powerful. To give you an idea of just how powerful it is, the "Schedule Calendar", "Sabermetric Reports" and "Favorite Toy" are all features implemented completely via the SDK, yet they present themseleves as core game features! Again, If you are interested in developing on the platform please send me a note. I'm trying to gauge interest.
