Hi Steve,
Sorry to hear of the troubles that you’ve been experiencing with RED lately. I hope to offer an explanation for some of the woes that have cost you time on the project.
You mention that using RED 4.3, you opened a RED 3.0.2 project file and then closed it without saving without saving, yet is became stamped or identified by RED as belong to RED 4.3. My guess is that you have the Auto-Save function enabled in RED 4.3. Can you check that? If this is the case you might want to disable that feature in the RED 4.3 preferences. Also, if you are worried about something like this happening again, you might want to consider duplicating the project file before opening it in another version of the software. I know this advice is a little too late but something to consider moving forward.
Regarding the other issue, RED is resolution independent and you should expect to be able to change a project size at any time. If you would like to send me a project file along with an example of the EPS that you are using, I’ll take a look to see if I can understand what the problem is. Feel free to send me the project and EPS via email (peterm@borisfx.com) as they should be small files.
Cheers,
Peter.
