We've been working on a stylesheet for a while, and a recent version started getting this error and refused to open. However, when we went back to earlier versions of it (which previously had opened fine) they also get the same error and refuse to open. We've lost almost a month of work on this. Any suggestions would be greatly appreciated.
This is an APP stylesheet, and it is built on another stylesheet which has been getting updated over time as well. We are working in AE Styler 6.0. We've encountered this error before but previously were able to go in and delete some of the page defs and then it allowed us to open it, but when we delete the page defs, now it still won't allow us to open it.
