I also had to give up using SharpCap for the same reason.
PHD2 also another align tool - Polar Drift Align that you could try as well. There's also a new static polar align tool in there as well, but I have not had much luck with it as yet, since it wants me to pick a particular star and I haven't got any idea what is what there.
It probably needs some form of plate solving to go with it to make it really useful.
Another option is to install Astrotortilla. It does plate solving, but also has a PA routine that does not require seeing the south pole. Can be useful for those locations where it's obscured.
