MPLAB ICD2 Error

It's been a while since my last post.

I am trying a new PIC - 18F2331 - and can't seem to get a compile to happen. I am using an ICD2 in MPLAB with PBP. All I'm starting with is flashing the old led.
I have tried the ICDDEFS(all of them) to no avail. I still get this:
"ERROR: Variable ICDRESERVED12 position request 1524 beyond RAM_END 767.Halting build on first failure as requested."

I had been using a 252 previously but wanted to get into the PWM stuff with the 2331.

Any ideas/help appreciated.

The '252 has about 1536 bytes of ram, the '4331 only has 768 bytes.
Cut down your variables. Try commenting some of them out and see what happens.

Have you tried ICDDEFS3.BAS?

It should read: ICDRESERVED12 VAR BYTE(12) $2f4

That one should work for the 18F2331.

I referenced the '4331, just noticed it's actually the '2331 that's noted above...
Regardless, both of them still have less ram than the '452.

Thanks for the replies.
I did have a memory issue and have now solved that(with help from a friend:).
