I've installed SP2 in many machines (more than a dozen), and I encounter this problem with CCE 2.5 (I don't use newer versions) on just ONE- I cannot know the reason, but on that very machine practically nothing works as it should after installing SP2, while on others I have no problems at all...
Sorry if this didn't help, but this is all I know for now.
The revolution cannot be a lever, or an essay, or tablaeu, or embroidery. It cannot proceed mellowly, piece-by-piece, gently, devoutly, simply and humbly.
