Last week, Update 1 for AutoCAD 2011 and AutoCAD LT 2011 was removed due to an issue with the Layer Manager that affected a small number of users. A hotfix is now available for those of you who applied Update 1 to your AutoCAD LT installation before it was removed. If you have not already applied Update 1, no action is necessary. A new Update 1 will be posted as soon as possible.Go to the original post...
