[TRNSYS-users] Trnsys3D error

[Serban Cristina]

I'm having problems with Trnsys3d plugin version 1_0_5_2 which is 
installed on Google SketchUp 8.
While creating my building, the 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

appears. I already installed and unistalled Sketch-up and Trnsys3d 
several times, and the error persists.
