Hi,

This is my first post, hopefully someone may be able to help.

I installed AutoCAD 2015 LT ( have full licence) for Mac a while ago and recently when updating my computer to OS X 10.10.3 I had problems (crashed). I had to use Time Machine ( back to a time before Yosemite install ) and then reinstalled Yosemite and all is OK - except my Autocad 2015 LT is no longer available. I re-downloaded Autocad 2015 LT and tried to reload onto my computer  - it attempted to install then froze.

I removed autodesk 360 and there was no other trace of the autocad software on my computer - still no success in installing.
