Game does not 'reset' map after you get an error?

[LGX]

I'm new to this game engine and I'm having some problems. Basically I have made a little test map that works just fine. I recently added two shadow casting spotlights that overlap, I got that "FATAL ERROR" message. Ok no big deal, I guessed maybe the engine doesn't support two overlapping shadow casting lights. The problem is however, when I remove the lights and go back to the way my map was before (back when it worked fine) I still get the error!

In other words, I'm still getting the error even though I reverted back to my old map that used to work. The only way to 'solve' this apparantly is if I redo all the configs, restart the level editor and save the map again. This is extremely annoying and time consuming, am I missing something or..? Why does the error continue to plague me even if I remove the cause of the error? That doesn't make any sense.

I doubt the problem is related to my PC, I work with many engines such as UE3, CryEngine3, Source and an indie OpenGL engine, they all work fine.

Help is appreciated.

edit:

I think the problem is solved, it didn't have anything to do with lights or the editor itself. I had 3ds Max running in the background plus some other stuff. I closed those applications and so far I haven't gotten any more errors.

What does the FATAL ERROR say?

[LGX]

Something about 'Renderer #0', I will write it down when I get it again.

This is really weird, for some reason my map works fine again, this 'FATAL ERROR' seems to have a will of its own. I will do some further experimentation to see if I can corner the bastard.

edit:

Not sure if this makes any sense, but I no longer get the error if I use the 'Save as' function rather than 'Save'. I used to get the error when using items, multiple shadow casters, certain meshes. But now they all work fine.

Have you done any scripting on this map?

[LGX]

No, it's just a plain simple map.

BTW I have made an edit to my previous post.

edit:

Meh forget what I said, the error is back. I am completely lost here. Just half an hour ago my map with two shadow casters didn't work, then a few minutes ago it DOES work. Now I remove the lights again and the map doesn't work (even though it did work before).

So much for work motivation.

edit:

Magically all versions of my map work again. Trolololo?

Is it possible maybe that background applications conflict with the engine? Maybe a firewall, virusscanner, modeling software?

Maybe try deleting the map cache files?
