Been seeing those for endless number of years. Not helpful is it.
FPSC is trying to tell us something. Its not good at common English responses or any kind of human readable/understandable kind (unless you know anything of its internal workings I Guess).
The messages presumably mean something to someone but no one ever seems to have had a definitive answer or listed what actual Runtime Error numbers specifically in each case might refer to as its issue to even provide a clue to end users?
Presumably FPSC makes a choice in its responses based upon some criteria or other but I don't think we users know what any of them mean.
Thus its a matter of keep trying something else for a fix but what is left up to the user to decide other than ask here by a long process of questions which often are not exact as I am not sure anyone knows the answer in each case. Its trial and error.
Maybe I am incorrect there.
I presume you have tried more than once. Try shutting down and then trying again. If its not a complete non starter engine issue then sometimes repeated attempts after installing, retrying and so on will get it to run. Sometime in the past when there are clearly bugs then they wont no matter what you do until the bug is corrected.
Presumably theres nothing wrong with your install and set up - and or level content - i.e. File paths, corrupt stuff and so on.
Is it only the one level the issues shows up in?
Try starting another simple level with some different things in it and see what happens with that. If that's OK then I guess its just that level has gone beserk.
Don't know how else to help myself other than say you need to keep trying things and go through a process of elimination.
There are those that said this day would never come. What have they to say now?
