Suddenly I have Simulink crashing when I use the OPC toolbox. When I open the OPC config block to "configure OPC clients", simulink gives the following error when I try to add an opc server (below the localhost window):
Configuration: Crash Decoding : Disabled Default Encoding: windows-1252 MATLAB Root : E:\Program Files\MATLAB\R2011a MATLAB Version : 7.12.0.635 (R2011a) Operating System: Microsoft Windows XP Processor ID : x86 Family 6 Model 12 Stepping 10, GenuineIntel Virtual Machine : Java 1.6.0_17-b04 with Sun Microsystems Inc.

Any suggestions how to fix this? It worked until recently!

I would recommend contacting MathWorks Tech Support about this.
