error while exporting a swf file from a game using the platform movement object

[Chokito]

Hi, I'm trying to export an swf file of a game that uses the platform movement object. I always get the following error:

Loading configuration file C:\Program Files (x86)\Clickteam Fusion Developer 2.5\Data\Runtime\Flash\Flex\frameworks\flex-config.xml
C:\Users\Chokito\AppData\Local\Temp\Fla4024.tmp\Ex tensions\CExtLoad.as(49): col: 12 Error: Call to a possibly undefined method CRunplatform.

object=new CRunplatform();
^

I'm using Fusion 2.5 with the updated version of the swf exporter. Is this a known bug? I belive the platform object is expected to work with the swf exporter, right? I'm attaching the original game .mfa file for reference.

I updated the Fusion 2.5 to the 280.28 build. Now the error does not appear, but the resulting swf does not work - it stays white all the time. Swfs created without the platform movement object work well.
