I am having similar/exact error condition as in the below post..
http://forums.ni.com/t5/LabVIEW/Error-Master-Copy-for-Type-Definition-Could-Not-Be-Found/m-p/1496866...
The *.lvbit file i am using was compiled in Labview 8.2.1 and I am now using 2009 version of Labview. Unlike the suggested solution, recompilation of *.lvbit file is ruled out due to lack of source code access.
Any help towards troubleshooting is appreciated...
