Initial Setup - Lines not showing

I recently downloaded the software and had trouble being able to see my previous drawings properly. It appears that the line thickness/weight is messed up. On my old drawings, the drawings/lines do not show up at all. So I went to the settings which I had done on the previous download and I changed the background color and so forth. My drawings/lines still did not show up. I was only able to get the lines to show up when I changed the line weight via Drafting Styles/Active Drafting Styles/Line Font/Line Weight. I have to click on "Display weight is graphics area" and increase the line weight to a min. of 13 in order for my lines to show. But the lines are still too thick and look terrible.

Secondly, in order to allow the printouts to come out right, I have to make other adjustments to the line weight under the Print menu... Additional Options, unclick line weights.

I don't know what changed from the previous version/download that I had or if the settings are just not set correctly. Can someone please help with the settings so I don't have these issues with line thickness, visibility of drawings, printout legibility?
