Pokemon Diamond Underground crash(?)

[lazysummer2013]

I am using iDeas 1.0.3.2 beta & I read some other threads and got my pokemon diamond to save correctly by itself so I can load off in-game saves. But when I try to go underground in the game, it says it needs to save and activate DS Wifi. When I got in it just said a communication error has occured.

I have the following plugins (checked):

OpenGL 3D
Default 2D Plugin
DirectSound Plugin
Wi-Fi Plugin

My comp spec:
Windows XP
Intel Core 2 Duo T8100
4 GB RAM
nVidia GeForce 9500M GS (512 MB)
