Hello. I am new to this forum and would be grateful for some advice.

My copy of 4.8 pro has been working fine for a good couple of years until yesterday, when it refused to connect. This has continued today and is very frustrating.

The status of most of my downloads says "need more sources" and a couple say "waiting for stable connections".

I have one small green bar and four red bars and it says "connecting".

My internet works fine and I cannot think of anything that I have changed which could have caused this.

I am using windows XP.
Anyone have an idea as to why this may happen and whay I could do?
