What to recover, Data Type: Files

Hello everyone
Ok, here it is in a nutshell.
1. The location of the backup files is on a network drive. I go to it using a login and password.
2. When I click on What to Recover I choose Data Type: Files
3. The Content calculates all the Items to recover with the backup Type of Incremental
4. Items to Recover shows 30,000+ folders, 500K files and about 300 gigs
5. When I click on Change (to choose what I want) I get the server name and a Plus to the left of it and nothing in the right are
6. I click on the Server name and still nothing shows up. If I click the Plus sign to the left of the server name it thinks and then nothing shows up under it even though the + has turned to a -
7. It takes about 15 minutes to enumerate the Items to Recover

Now, do I need to click on Change and just wait another 15 minutes for it to show up in the right side?
