Illegal exception when trying to test game

[Nastor]

Hi! I'm new to the forums, but not new with AGS.
When I try to test the game I'm currently working with, I get this error:

---------------------------
Illegal exception
---------------------------
An exception 0xC0000005 occured in ACWIN.EXE at EIP = 0x0043104A ; program pointer is +32, ACI version 2.70.864, gtags (148,22)

It started a few weeks ago, while I was working with v2.7.0
I have tried upgrading to 2.7.1 but nothing, could anyone help me?

At what point does this happen? As soon as the game starts up, or when you enter a particular room?

Would it be possible for you to upload your game for me to take a look at?

I could upload it, but the game is in spanish, so are the comments of the code, and I don't think you would be able to understand it, but If I'll upload it if you wish.

I was trying to found the error, and I realised that it happens sometimes when changing the player room, or if there is an event that transports him to another room, althought it's not triggered.
Moreover, it happens only in some rooms.
Any idea?

Is there a room where it happens quite regularly? If I was trying to recreate the error, would it take long for it to happen?

It doesn't matter if the game is in Spanish, that shouldn't stop me from being able to find out what the cause of the problem is -- so if you would be so kind as to upload it, that would help a lot.
