Not sending MMS on C600

[Guest sukonik]

Hello people,

So I am lost with this one now.

My C600 wont send MMS. THis has worked before.

I have changed the registry key:

HKEY_LOCAL_MACHINE\Software\ArcSoft\ArcSoft MMS UA\Config\UI\ReservedSpace

to the value 4132 from 1024

this I'm sure would of fixed the problem, but i'm still getting not enough space to send message!

Does anybody have any ideas?

Thanks

Carl
