Error : Index and length must refer to a location within the string .

[Marvino]

It was working without any problems until I decided to update to 2.3.0 version then I started to get this error after each time I run any of the presets. Here's the full error text :
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">
</system.windows.forms></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.

Hi, thanks for the report. I have found and issue when using file source path as destination path.
Latest executable addresses this problem, you can replace your current one with it.
