Windows 8.1 - SecuROM issue

After upgrading to Windows 8.1 and installing SPTD 1.84 and DTTools Pro 5.4 (both clean installs, of course), it seems that SecuROM emulation isn't working well anymore. On Windows 8 / SPTD 1.83 / DTTools Lite 4.47 there were no issues, simply create a SCSI drive, mount the image, enable SecuROM emulation and off we went, but now it's detecting emulation software again. The ISO has been properly burned and works on Windows 8 / Windows 7.

Are there any log files I can check for troubleshooting?
