Only took about 50 minutes to download everything on the fiber connection at home.

I have successfully downloaded all four parts of the SONAR files in less than an hour on cable, and the Read Me and also the Video I purchased.  

I was having difficulty downloading parts 2 and 3 while everything else went smoothly and quickly.

Parts 2 and 3 had messages like server not found for me anyway.

The issue cleared and they downloaded fine.

My downloads seem to be moving right along. I'm not sure where CW is sourcing it's store DL's from, but I'd expect that any dodgy behavior is due to local network conditions along the path your DL is routed. DL's are usually straightforward for a server, less work than serving pages as it doesn't need to hit a database with queries, and the OS can cache file reads.

I decided to try downloading the program, but as expected it's taking forever, I already have about two hours into it and I'm only halfway thru part 2. I hate downloading.

I'm getting a speed between 350 and 480 KB/s. I started downloading at 10:30 AM and I'm just about finished with the last one - Addictive Drums - at about 6:00 PM.
 
So lets say about 8 hours.
 
I downloaded the loops, but not Dim Pro as I already have it.
 
It is said the loops are the same as in X2 (they are even called X2 Loops) but the MD5 hash is different so I downloaded.
 
I copied all my media content into the X3 library before installing the new loops so I should get new and old data.
 
I've installed X3, but not restarted yet or made the first run.
 
I'll do that after the Addictive Drums download and install.
 
I got all my VST3 plug-ins set up as well.

It took several hours. I ran it overnight and it was ready when I woke about 6:00am.
I am in the Philippines and my connection can be up to 5Bbs but is usually slower around 1.5-3Mbs
 
If I was near Manila I'm sure it would be faster.
