Print command erroring with 'Undefined function or method 'findprop' for input arguments of type 'struct'.'

Apparently my 2010b version and my 2011a version were getting their wires crossed - so what Walter was saying was on the right track. Not sure how to best fix this - but I put a 2011a folder with all the files with the 2010b folder (the default install location apparently changed between these two versions), and for now it is working.

Thanks!

Matt
