I'm having a lubuntu-64bit and installed MySQL-workbench to open the EER model. but it just doesn't open up..
It shows error
Error unserializing GRT data
error unserializing object (invalid struct)
The same EER file opens fine in windows.. I'm new to this I need to create Database using these on this machine please help..
I was facing the same issue, at last i just close the application and restarted, it resolved the issue.
