When I imported my 1.x effects into 2.x, I discovered that the effects type (2nd column) was incorrect. For instance the Vocal Plate (which I use a lot) had Chamber as the type. So what I did was make a plate fx in 2.x and exported it to a file. Then I brought both files into a notepad (eg Notepad++) and copied the parameter section (lower section) of the 1.x file to the parameter section of the 2.x file, then imported the 2.x file back into the library. The Scene Parser tool can also be used to do this.
