Illustrator can't finish previewing; not a memory issue
Just installed Illustrator CC and I am trying to work on a simple illustration but it has switched itself to outline mode and will not return to pixel or overprint preview. It gives the error "Can't finish previewing. Could not complete the requested operation." The common cause of this problem is lack of memory or insufficient scratch disk space, but my computer has 8GB of very fast RAM and my scratch disks are mostly empty and multiple terabytes each. My document is fairly simple; I am making speedo and tachometer gauges for my car, so the illustration is simply lines, guides, and a small amount of type on a single artboard, and one low-resolution .jpg I am using as a template. One thread I found suggested that TrueType fonts can cause a problem for Illustrator so I changed all the type to an OpenType font to no avail. Any suggestions are appreciated.
Specs:
Windows 8 Pro
Intel Core i3 at 3.35Ghz
8GB DDR3 1600 RAM
GeForce 560 GTX
Illustrator CC installed on 2TB, 7200RPM drive; this drive is also my primary scratch disk
Secondary scratch disk is a 1.5TB USB3.0 external
System drive is a 128GB SSD so I do not want to use it as a scratch disk
