Hello.

I am experiencing serious problems with AutoCad LT 2014 on my macbook Pro (Yosemite).  

1. If i click on a DWG file to activate the software nothing happens.

2. Once the software is open, I can open a DWG file, but if i then try to open an additional file the whole software crashes and closes down.  This pretty much means that the software is unusable.

Can anyone help?

Thanks

Neil
