[Help] Resize .m2 problem

[ddftrick]

I am trying to increase the scale of Frostmourne using Glitchy's MES

When I use the resizer option and click on enlarge model i get this error message.

Unhandled expection has occured in your app. If you click continue, the app will ignore this error and attempt to continue. If you click quit the app will close

Arithmetic operation resulted in an overflow.

If i click continue the model stays the same size.

What can I do to get this to work, and if not what other options do i have to scale the sword size up?
