I count 36 characters in your TC name.. This is not good.
Please reduce the name to somewhere less than 10 characters if possible.. 20 at most.
No spaces, pure alphanumeric.
See C9 here for why the present name is bad.

Also if your wireless name is the same.. change it to short, no spaces and pure alphanumeric as well.
Then manually mount your TC disk.
In finder use top menu, Go/Connect to server.
Type in AFP://TCname.local (TCname is your new short name. Local is the default domain).
Or it can be even better to use IP if that doesn't change.. ie TC is in router mode.. and by default is 10.0.1.1 then
AFP://10.0.1.1
Then apply and you will be asked for the TC disk password.. default is public but whatever it is you set. Make sure you save it in your keychain.
The TC data share should then mount.
And small comment about using the TC for files..
TC is designed for Time Machine. It is not a NAS.. it has no backup.. it is slow to spin up and fast to spin down. Using live libraries will result in corruption and loss of your entire library in the case of iphoto.
Please be very careful. Do not jump in and think very carefully. Time Machine cannot backup any network drives including the TC. You are going to have issues with backup if the TC is only location for your files.. it is unsuitable for this. CCC can backup to another drive.. but where will that be.. USB plugged into TC you will experience new visions of pain and suffering as the backup takes almost as long as digestion by a Sarlacc.
Pondini has some pointers here.
