I have draftsight professional and been signed up since April last year, now all of a sudden I'm not able to print - I click on it and nothing happens, Tools/Options is the same - when I click on it nothing happens, and certain Format options don't work either - for example can't utilise Dimension Style - nothing happens when I click on it. Really weird in Format - Line Style and Color work but Line weight doesn't.

What should I do?
