Cannot connect to database (10.2 XE) with old data files

Question

Hi,
I was running my database for a while but a couple weeks back it started failing - as in I can no longer connect to it. I tried moving the datafiles (all files under \oraclexe\oradata\XE ) and reinstalling and that makes everything run again with the default database files but when stop the database and copy my old files back in and restart - presto I can no longer connect either by jdbc or by apex ( 127.0.0.1:8080/apex ). My css log file has this in it after I resttart the database and try to connect to apex:

2011-12-28 17:07:20.084: [ CSSCLNT][3280]clsssinit: error(33 ) in OCR initialization
So, how can I rescue my data or fix what I assume is a corrupted datafile? I had a backup on dvd but now I can't find the dvd so I'm stuck.

Hi,
Thanks for the replys,
My instance is running in the exact place as before.
When I try to run the commands in the trc file I get up to a point but then get errors.
The following commands seem to work:
STARTUP NOMOUNT
CREATE CONTROLFILE REUSE DATABASE "XE" RESETLOGS NOARCHIVELOG
MAXLOGFILES 16
MAXLOGMEMBERS 3
MAXDATAFILES 100
MAXINSTANCES 8
MAXLOGHISTORY 292
LOGFILE
GROUP 1 'E:\ORACLEXE\APP\ORACLE\FLASH_RECOVERY_AREA\XE\ONLINELOG\O1_MF_1_4WK0TDM0_.LOG' SIZE 50M,
GROUP 2 'E:\ORACLEXE\APP\ORACLE\FLASH_RECOVERY_AREA\XE\ONLINELOG\O1_MF_2_4WK0TL5T_.LOG' SIZE 50M
-- STANDBY LOGFILE
DATAFILE

-- Configure RMAN configuration record 2
VARIABLE RECNO NUMBER;
EXECUTE :RECNO := SYS.DBMS_BACKUP_RESTORE.SETCONFIG('CONTROLFILE AUTOBACKUP','OFF');
work but I can't get past it...

eg the command : RECOVER DATABASE USING BACKUP CONTROLFILE
produces this:

and the command ALTER DATABASE REGISTER LOGFILE 'E:\ORACLEXE\APP\ORACLE\FLASH_RECOVERY_AREA\XE\ARCHIVELOG\2011_12_29\O1_MF_1_1_start.ARC';
produces this:
SQL> ALTER DATABASE REGISTER LOGFILE 'E:\ORACLEXE\APP\ORACLE\FLASH_RECOVERY_AREA

ERROR at line 1:

What is the trick to getting it to open an archived log?
