AutoCAD opens but i cant create anything

[Anonymous]

Hallo,i downloaded the  AutoCAD 2017 demo version about 2 weeks go. Everything was running perfectly until 2 days ago when i open autocad the main screen where you draw crushes but the rest is fine. Has anyone had something similar happend to him. Any tips to take it back to normal?

thank you for your time!

Use RECOVER command to open the dwg file and see if the problem is a corrupt drawing.
If the file has Xrefs use RECOVERALL command instead.
