Here's something that has me jumping up and down. I have tried to open files in 2018 after subscribing to SoftPlan + and upgrading to 2020. All my .spd and .spp files that were saved in 2018 will not open anymore in 2018. I was under the impression that you could still run 2018 and open all the projects and files saved in 2018. I know that if you save any project or file in 2020 then you have to use 2020 from then on to access that project or file. I have not saved these files in 2020 but when I run 2018 and open any 2018 file a popup comes up that says "The project was created with a newer version and cannot be read by this version." The problem is that the project was never created by the newer version and not saved in the newer version in the first place. It was created in 2018 and that is what I'm trying to open it with, not 2020. It's like all .spd and .spp files have been converted so that 2020 has to be used. Like I said, jumping up and down.
Why don't I just use 2020? I just don't feel like mixing and matching. I want 2018 to stay 2018 and not half 2020 and half 2018. That's a recipe for disaster. Got enough issues with file management already. And I don't plan to use SoftPlan + forever. I already own 2018 and it works for me. Or used to.
SoftPlan is a great piece of software but sometimes the random glitches and haywires that come out of nowhere drive me crazy.
