I'm porting my project from 0.85 to 0.9. I got my solution to compile, but when I try to run it, I get a message starting with this text:

The same window shows other similar messages, regarding multiple entry points.
To make things more simple, I removed from my project several files that do not affect its functioning. So, while porting I did not include all files. Maybe, some of the excluded files have been introduced in the last version, while they were not present, or were not useful, in 0.85.
Does someone have a clue?

I solved it myself.
There was a GuiRenderer.program file in my old folder leasing to the error.
I removed it and now it runs.
