Pipltool question

Hi,

I am trying to develop a plugin and I use the CS4 sdk and After Effects CS4 9.00.346 (I know it is old, but the trial version of CS6 did not start, and chatting with the help desk was really painful and unsucessfull)

My .r file is taken from the Skeleton example and includes the "AE_EffectVers.h" Header.

The pipltool.exe fails with the following error: "Line #6 Undefined Symbol AEFX_API_SUBVERS, line 6" in AE_EffectVers.h.

This line looks like this:

#define AEFX_API_SUBVERS      ' '

Did anyone stumble across this error and can provide a solution, please?
