You may have to delete it and start over... but I would wait a while.... every night they seem to be overruned when those bloody english start downloading.
Also, make sure you have enoug FREE drive space... sometimes thing's are not always the fault of the British.
If you are going from a 32 bit to a 64 bit, I would just get them to send you a DVD and avoid some problems. Since you can't seem to download you have a good excuse for not being charged extra.
Otherwise, could anything be stopping it like some monitoring software or firewall or anything else. If you watch the performance indicators during the download, do you see any abnormal activity when the download stops?
Does you ISP put any limits on downloads? How big are the files you do get?
You might try switching browsers.
There may be a number of times you can attempt a download. If it doesn't finish, I don't know if it counts or not.
I assume you have read the tutorials and stickys about making a bootable DVD from the downloaded files and you see no problem with that?
Did you try a different browser. It may not let you if there is a authorization method being used. But it might just take a cookie change to get that. If you install Firefox, it offers to import all the cookies, but there may be a bad cookie you do not want--hard to say for sure.
I am running DLMWin7Pro64US.exe at it just stops at 68%. I honestly don't know what else could be causing this issue.
Any other suggestions would greatly appreciated, thank you!
