[TRNSYS-users] Error with Trnsys3d plugin

[damien.palacios@gmx.fr]

Hello,
Whenever I try creating a simple project (a cube-house with a window), I can't save it and re-open it without getting this error :

Sorry...the plugin has encountered an error.  This error may cause unpredictable behavior in the plugin--continue this session with caution!  It would probably be a good idea to exit SketchUp and start again.

For help, please contact the TRNSYS newsgroup by https://www-old.cae.wisc.edu/mailman/listinfo/trnsys-users .

 When reporting a bug, please include the error message and backtrace below (scroll down):
