Cannot connect to Oracle 11g XE through SQLPlus

Currently Being Moderated
Have been trying to resolve this all day. I have Oracle 11g XE installed on my local desktop (Windows 7 64 bit)for which I have been using for over a year for development. The recent "Sandy" storm killed the power at our office for a week. Upon returning to the office, I can not seem to connect to the Oracle on my desktop from my desktop. The only thing that supposedly have changed was the router re-assigned IP addresses. However, I have modified my tnsnames to reflect the proper IP address. Still I get the below error trying to connect through SQL*Plus (without specifying the service):

ERROR:
ORA-01034: ORACLE not available
ORA-27101: shared memory realm
Process ID: 0
Session ID: 0 Serial number: 0

When I try to specify the service name "...system/password@xe", it gives me the following error:

SQL*Plus: Release 11.2.0.2.0 Production on Thu Nov 8 19:54:17 2012

Both the "OracleServiceXE" and "OracleXETNSListener" has been started.

Would really appreciate it if someone can help me resolve this. Thanks!
