RDWorks - can't open it's own saved files?

Don’t we have codes of some kind for lightburn? I feel like I recall seeing a post about that at some point

Not at this time. In order to get the discounted member codes, we need the activation key for our license and no one has been able to locate that. In about 5 months when we buy new annual licenses, we can set it up.

I am getting this same error on the computer attached to Blitzen. To test & confirm, I created a new .rld file, closed it, and immediately attempted to re-open. Same error.

Version installed on the PC is v8.01.35
