Can't open X6 project in 2018

Today I tried to open a rather complex project originally created in version X6 in the new 2018 version and got an error saying: "Error reading [path+filename]". Clicking OK in the error box clears the message and the workspace opens to a blank window.

Luckily I still have X6 installed and was able to open it in that version. So far, this is the only CDR from X6 that won't open in the new version. I really don't want to have to keep X6 installed just for circumstances like this. What could be wrong?

  • Open in X6 delete 1 complex bit then save a version. Try opening in 2018. Repeat steps until you find the culprit. More than likely a special fill or transparency or even a font can cause this.
