Trouble getting compiled samples to run

Question

Hello,
I'm new to the after effects sdk but not to programming or sdk usage in general, but I'm having trouble getting the samples to work.
- I've got Creative Suite 3 production premium
- I've got After Effects cs3 sdk
- compiled using visual studio 2005
Seems to compile ok, but when running nothing seems to happen in most cases. In some cases I do get an error message (such as in easycheese) it returns the following error: "After Effects error: AEGP magic error (5017::10)"
I looked up magic number in the docs and the only reference I could find to it simply said something to the effect of "don't change it".
I've got a working script and an idea for a second project, both of which I'd like to implement using the sdk, but I can't seem to get past this first obstacle. Any help, that anyone could provide would be greatly appreciated.

I'm seeing a problem in the MessWithMarkers function, where it calls AEGP_DisposeStreamValue. This problem doesn't happen in AE 7.0, but does in CS3.
For some reason, the behavior of AEGP_GetNewKeyframeValue has changed between 7.0 and CS3 so that it doesn't return the streamH in the AEGP_StreamValue struct. And when the sample calls DisposeStreamValue, it wants a valid streamH. So you can update the sample for the new behavior by putting a check before the DisposeStreamValue call:
if (value.streamH){
ERR2(suites.StreamSuite2()->AEGP_DisposeStreamValue(&value));
Other than that, the sample seems to run normally. You'll need to put some keyframes on the first layer in your comp, and the Easy Cheese effect will modify those keyframes and generate markers.
