Straight from the mouth of Autodesk: uninstall update 2.
"Early this morning I was made aware of a new change request that is tracking incidences of random crashes like your's in AutoCAD LT 2009 after Update 2 has been applied. Currently we are rapidly receiving error reports ranging from New Zealand to the UK at the current rate of 37 reports over the past 24 hours.
Development is asking for a reproducible case to unravel what the root cause is. If you can reliably duplicate the conditions where the crash occurs that we can relay to development, please send details. Otherwise, you should uninstall the Update 2 that appears as "AutoCAD LT 2009 - English Version 3" in the Add or Remove Program applet until we can correct the problems you've been seeing.
We apologize for the inconvenience. This has become a hot issue that development is actively attempting to resolve."
Also, I had to click the box that says "Show Updates" at the top of the Add/Remove Programs window in order to see the English Version 3. After I uninstalled, everything was still customized as it should be (although I recommend backing up your CUI file and other custom files you may have changed just in case). We're going to wait for update 3.
If you uninstall, don't forget to add update 1, the Open/Close Fix, and the WAN accelerator. These are readily available from Autodesk's website.
Be sure to send any and all error reports. Autodesk doesn't know there's an issue and will not address comments left on the discussion boards only. Their development team works off of the reports and a few issues brought up by phone or email support.
