This article applies to:
This bug has been corrected in E-Prime 2.0 (220.127.116.113).
When using E-Prime 2.0 Professional to open E-Prime 2.0 Standard experiment (.es2) files, you are prompted to either maintain the Standard file format or convert to the Professional file format:
If you convert the file, E-Prime opens the file in E-Studio as a Professional edition file. However, some E-Prime 2.0 Professional features, including Task Events and Package File calls, are not available.
Update to E-Prime 18.104.22.1683 or later.
This workaround is intended only for those who are unable to update to the version of E-Prime that contains the bug fix:
Close E-Studio, then launch E-Studio and open the experiment file. All Professional features will be restored.
