Unhandled exception has occurred version 1.5.0.41 BUT NOT with 1.4 version PLEASE HELP

Good afternoon to all..

Firstly compliments where they are DUE.... WELL DONE this is such a great piece of software thank you..

I have just upgraded to the new version of 1.5.0.41 as it has the ability to read from the document feeder of my Brother MFC620CN

Sadly everytime i try and use the this version the I get;

Unhandled exception has occurred, this is with either with the flat bead or feeder (beta) selected.

However my ealier version works okay...

PLEASE PLEASE HELP AND ADVISE, if I am just doing something stupid, sorry but please help..

See the end of this message for details on invoking
just-in-time (JIT) debugging instead of this dialog box.

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

For example:

<configuration>
    <system.windows.forms jitDebugging="true" />
</configuration>

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.
