'An unknown error has occured'.
And I couldn't tell you why!
It's a file I have used many times.
I just wanted to make some adjustments (after six months of doing nothing with it).
And I'm certain that it worked before.
I hadn't even started changing anything yet.
I just opened my file in MMF2-Developer and clicked:
File / Build / Application
The progress bar at the bottom of the screen is working and when it's about 80 percent done, this annoying little pop-up screen pops up!
I have no idea what the problem is.
I even tried reinstalling MMF2-Developer on my laptop and try to open the file there. But again with the same result.
My file is about 15 Mb in size, so uploading it here won't work, I suppose. But I'm baffled and, quite frankly, really annoyed, because it cost me about a year of weekends to create this peace of software and I really don't want to re-create it!
Can somebody offer any help?
