This bug has been corrected in E-Prime 2.0 (126.96.36.199).
When working in EP2 Standard and attempting to add an additional device when one already exists (like a second Display), the error message has a typo. The typo will be an incorrect edition of E-Prime. For example, if you are using E-Prime 2.0 Standard, the error message may say "E-Prime 2.0 Professional".
Upgrade to E-Prime 188.8.131.52 or later.
