Yes that's a big help John. The trees are another issue which I see is covered in another thread here. I originally selected them as the best I could find but now they show up as translucent cross shaped trees which it seems are called Billboards so I will have to find something to replace them. I don't want those weird looking trees which swayed in the breeze as though they were made of rubber ! I've imported my routes from TRS12 and saved the whole TRS12 software to a USB stick to keep it safe as I thought I had deleted it but like I said there it was hidden away. If I can get rid of those horrible orange boxes that will be a good start.
The newer Speed Trees don't bend in the breeze like the old ones do. Yay!
To narrow down the orange boxes, go into Content Manager.
Content Manager is different if you haven't noticed already, but it still works the same. For starters, you need to set things up so they're easier to work with. The first thing I did is add in all the columns. Right-click on one of the columns, and choose one of the categories. Add them all by repeating the process. Once that's done, you can spread them out, and place them in any order you wish. I like this particular layout.
Type, Status, Asset ID, Name, Build Version, File Size, Author Username, Modification Date, Installation Date, and Upload Date.
Right-click on your route, and choose view dependencies.
Another window will open up showing the contents.
Click on status until you have all the blanks, or and Available for Download showing at the top. You maybe lucky and only have items to download.
If you have items to download, highlight them, right-click, and choose download. This will install the asset.
If you have any unknown, you need to search those Kuids in your old data, and at other sources.
There's plenty of variations on this theme with many more filters you can setup. I don't want to overwhelm and confuse you by giving you way more than you can chew at once.
