Roborealm crashes upon running Lego NXT module

I have inserted a sample RR program that I have found to crash once I insert in a Lego NXT module. I have taken part of the example for the Red Object Detection for a test. As you will see in the sample, when you move a red object to the directions up, down, left, right or center, the variable direction changes. As a key, 1 is up, 2 is down, 3 is left, 4 is right and 5 is center.
I am testing to control my robot's movements by moving a red ball. The program is working, but it crashes after I specify the direction variable and click "send".
I have tested the module by itself, not within any program. There is no problem, it works as it should.
Fore reference this is my NXC source code for the receiving end of the program:
//up 1, down 2, left 3, right 4, center 5
task main()
{
int i;
while(true) {
ReceiveRemoteNumber(0, true, i);
NumOut(0, LCD_LINE1, i);
switch(i)
{
case 1:
OnFwdReg(OUT_AC, 40, OUT_REGMODE_SPEED);
break;
case 2:
OnRevReg(OUT_AC, 40, OUT_REGMODE_SPEED);
break;
case 3:
OnFwd(OUT_C, 40);
Off(OUT_A);
break;
case 4:
OnFwd(OUT_A, 40);
Off(OUT_C);
break;
case 5:
Off(OUT_AC);
}
}
}
*the mailbox specified 0 is 1 in RR and NXT-G

I will narrow down the problem a bit further. I am assuming seems that the problem is coming from the CScript because when I try to send a variable without the use of its values being modified by Cscript, it runs perfectly.

Zack,
We came across a problem related to that module. When causing a syntax error, fixing and reloading would cause the picco C to crash. We've made that fix and uploaded a new version. Can you try that latest out and see if your problem continues.
If so, can you send us the CScript code that you are using in RR?
Thanks,
STeven.

Apparently, the problem still persists. The program was still running fine up to the moment when i plugged in my NXT via USB and turned it on.\
The source code for the NXC program:
task main()
{
int i;
while(true) {
ReceiveRemoteNumber(0, false, i);
TextOut(0, LCD_LINE1, "direction");
NumOut(0, LCD_LINE2, i);
}
}
