I have been happily using P B&R 12 Free for a few years now on my Dell Precision M4700 (had to choose safe boot mode however to avoid a crash). But since this morning, I can't no longer use it, it says "DPMI error" when I choose B&R option in the main menu. What has changed on my system since the last successful run, a couple of months ago ? 3 things: Windows 7 updates (as usual) - should be transparent for B&R Increased system memory from 12 to 16 GB Added an internal Sata drive (SSD, non-OS); no change to the system drive. Any clue ?
