XE release 11.2.0.2.0 on Win 7 64

Question

I installed XE release 11.2.0.2.0 on a Win 7 64 machine. I have created a test environment and I was able to log into apex and start my training. I tried to log in using the 'connect' command within the 'Run SQL Command Line' window using first my SYSTEM username/password config and my test environment login credentials. All received the ORA-12154 error. After some research online, I think the tnsnames.ora file and an inability for oracle XE to handle parenthesis () within the file name may be the issue. Not sure, but I would like to run my test environment through both the browser GUI and the command line to practive. Any thoughts?
My tnsnames.ora file was located here: C:\oraclexe\app\oracle\product\11.2.0\server\network\ADMIN
The contents of the file is as follows:
XE =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = Office-PC)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = XE)
EXTPROC_CONNECTION_DATA =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
(CONNECT_DATA =
(SID = PLSExtProc)
(PRESENTATION = RO)
ORACLR_CONNECTION_DATA =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
(CONNECT_DATA =
(SID = CLRExtProc)
(PRESENTATION = RO)
)

Post a copy-paste of sql command line session when trying to connect.
You don't happen to have a @ sign in the password?
Example from successful 'connect':
