Files created in rdworks were getting this error when opening them back up later. This was true whether the file was opened from a jump drive or saved locally
A potential problem is the version mismatch. It’s very likely that I have a later version than what is installed at the Makers Space. I am unable to physically make my way into the space until this saturday (05/28/2022), however if someone is available to view the version for me. I might be able to download the appropriate version and try to open some of the files I created on the Makers Space’s computer.
Pressing the “Help” tab at the top should open up a pop-up which contains the version number at the bottom. (See image for context).
So, @Casey_Hewens helped me figure out a work around.
(Probably the better work around solution)
Using Adobe Illustrator, if you export the file as a .ai (Version CS4). You can seamlessly import that into the RDworksV8 here at the maker space.
(Potential, untested solution)
I copied the RDworksV8 folder from the Maker Space and will install it on my laptop. Create a play file and see if the file format error exists. I choose to copy the Maker Space folder because I couldn’t find a website that appeared legit and wasn’t a torrent for the specific version of RDworkV8 being used at the Maker Space.
