I started the update the day before yesterday, continued with it this morning and had about 1.5hrs to go. I came back to the PC this afternoon to download the last bit and it now indicates I have to download the whole lot again. 17.4GB
This is ridiculous. It seems once you have downloaded part of an update and IPACS make a change and add another piece to the update, the bloody thing starts from scratch not a happy chappy at the moment.
