May Allah subhanallah reward you for all of your efforts. Ameen
Finally. I have the dvd 1 and 2. I downloaded three and started to extract it and I got the browser box that says enter the next part can you tell me what to do from that part to get it to completely extract. With dvd 2 it went smooth with no problem. Inshallah I can fix it with dvd 3 so I can understand how in case it happens with the others.
Right, this could be because of two reasons:
1) You haven't downloaded all the parts, DVD 03 has 14 parts in total, so make sure you have them all and then try the extraction process again.
2) You have downloaded them all but the parts are not located in the same folder, for example Part 1 maybe in My Documents, while Part 2 is on the Desktop.
This means you need to have the whole 14 parts in the same folder, and then extract the files. This will mean that it will not prompt you for a box saying "Sister, you have this part missing".
So my suggestion is:
Move all 14 parts into one single folder and then extract the files and Insha'Allaah it should be fine.
If not, post back the problem encountered and Insha'Allaah anyone who has had the same problem can also help and i will try my best too.
