#76 Errors with reopening file

[leon10]

Having problems with reopening file –
Always is displayed error:
''Error Loading File C:/Program Files (x86)/Google/Google SketchUp 7/Plugins/OpenStudio/lib/Startup.rb
undefined method `input_object' for nil:NilClassError Loading File OpenStudio.rb
undefined method `input_object' for nil:NilClass''

And when I press OK, later for every command I try to work with it is displayed:

''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 visit <http://openstudio.sourceforge.net> to join the user support mailing list, browse the list of known issues in the bug tracker, or post a new bug report.

I cannot make any changes to model in Open Studio...
When I'm drawing model in Open Studio, need to start every time from scratch.

Thank you for your quick respond
