org.lwjgl.opengl.OpenGLException: Cannot use Buffers

[Wolftein]

When i try to use VBO, im getting this error.

Exception in thread "main" org.lwjgl.opengl.OpenGLException: Cannot use Buffers when Array Buffer Object is enabled
        at org.lwjgl.opengl.GLChecks.ensureArrayVBOdisabled(GLChecks.java:90)
        at org.lwjgl.opengl.GL11.glVertexPointer(GL11.java:2742)

        ARBVertexBufferObject.glBindBufferARB(ARBVertexBufferObject.GL_ARRAY_BUFFER_ARB, vertexID);
        GL11.glVertexPointer(3,renderBuffer.getOffsetPosition(),sharedMemory.asFloatBuffer() );

im using Interleaved Arrays

Your getting that error because you're calling the wrong version of GL11.glVertexPointer(). The version you're using is for using arrays, not VBOs. The version you want to use is GL11.glVertexPointer(int size, int type, int stride, long pointer_buffer_offset).

Take a look at http://lwjgl.org/wiki/doku.php/lwjgl/tutorials/opengl/basicvbo for a simple tutorial.
