I've searched the forum for this problem and did not find any that were the same as my problem. If this has been previously addressed, my apologies.
I'm using the Software Center in 13.04 to download and install packages. So far so good. I've had no problems with several packages. However, I purchased 2 packages (Vendetta Online and Amnesia: Descent into Darkness) and neither of them will download or install. I've now been trying for more than 2 weeks.
The download will start and data transfer will be very quick for the first 20 meg or so then it slows to a crawl and finally times out and the download fails. The data downloaded to that point is lost. I can start the process over and get the same results.
While having this problem, other packages can be installed with no problem. Access to the web remains quick. Other files can be downloaded and apt-get has no problems. It's just these particular purchases.
I'm open to suggestions. Is there another place to get the games? Should I be using or changing my repositories? (Using the USA default servers.)
I'm really stumped.
I did contact the game developers and they sent me here.
I did contact AT&T and they tested the DSL and reported that it was working great.
Speed tests using speed test sites show that my connection delivers a reliable 5+ MBs of data.
Thanks for any help or suggestions.
