New install of LT2011. It has been working fine for a week. Now upon opening a drawing file, the first time I save the plan it immediately converts to Read Only file, therefore I cannot save my work. I have done one re-install with no fix.
From within LT use the File; Open from the dropdown or Icon.
Next to the Open tab at the bottom right is a Down Arrow, click this and you should see the options Open and Open Read-Only
If you click Open does your problem go away?

I performed a system restore and so far, so good. I have just started installing additional programs on my new hard drive and something must have changed with one of the installs. Problem seems to be resolved for now.
This thread was started over two years ago so I am guessing the System Restore worked for the OP since they did not come back to the subject.
Have you tried a System Restore to a day, week, month ago?
See if that made a difference?
