Migration from sqlserver 2005 to Oracle 10.1.0.3

Question

I'm new to the migration workbench. But I was successful in converting our sqlserver 2005 db to Oracle 10.1.0.3 using the Offline capture method. This isn't a terribly complex db - 100 tables, many are empty. The trouble started when I tried to convert it a second time. True, there was an additional table, and several tables were populated with more data, but I didn't even get past the 'Load Database Capture Scrpt Output' step.
In preparation for the 2nd migration, I dropped all the SS2K5 tables from the Oracle id I was using to house the migration repository. I deleted the repository as well. So the userid was 'clean'. I set up a new directory to house the scripts that are generated.
1. Created a new repository. Checked that the MD% tables were indeed created.
2. Ran 'Create Database Capture Scripts'. Checked the files - they were fine.
3. Ran the omwb_offline_capture script against the Sqlserver db, from the directory where the scripts were created. .ERR files all empty. .DAT files exist - things are fine.
4. Logged on to the Oracle connection where the repository resides. Clicked on 'Load Database Capture scripts'. In the popup, I provided the directory path & name of the .ocp file. And the 'Capturing Database' popup displays, but the progress bar isn't moving back & forth. But, if I check in the directories where the .DAT files were generated (in 3.), I see that the .XML files now exist, with the proper timestamp. Also, if I log on to the repository userid, I see that the SS2K5 tables have now been created. So something did indeed happen. But I don't see any list of things being created. (On the original successful migration, I would see entries for nn Tables, nn Foreign Keys, etc.). One point I noticed on the successful migration - the foreign keys part of this step took 2 hours. There's only 224 foreign keys, so I thought that was odd.
I don't know how to go further here. Anyone have any ideas?

Hi there, and thanks for the reply.
I'm using sqldeveloper 1.5.0.53
I tried it with a new Oracle schema as the migration repository. Same result.
Running sqldeveloper.exe from the command line doesn't give any error. Is there a file somewhere that an error might be written to, and I'm not seeing it?
I left the 'Data Capture' popup running overnight & this morning, it was in the same state - no progress bar action, no messages about items being captured, nothing in the 'Captured Objects' pane. So I hit 'Close', and in the message log at the bottom of the screen, I get
oracle.dbtools.metadata.persistence.PersistableObject.doInsert(PersistableObject.java:238) <timestamp in here>     
" (the above line is repeated forever). I eventually have to kill Sqldeveloper 'hard' - eg clicking the 'x' in the upper right corner.
Prior to killing, I can scroll to the bottom of the list of 'forever' lines, and the following 2 lines are displayed:
OALL8 is in an inconsistent state                                                  <timestamp in here>          
oracle.dbtools.metadata.persistence.PersistenceException: Protocol violation               <timestamp in here>          
On the Logging tab I see this:
Level          Sequence     Elapsed          Source                                   Message
SEVERE     32          0          oracle.dbtools.raptor.nls.OracleNLSProvider     Error loading nls:Protocol violation     
I'm completely lost!
Would I get this kind of problem if, for some reason, no db objects were present in the output generated on the Sqlserver side?
I notice that, after shutting Sqldeveloper down hard, it doesn't restart easily. I get the product screen, then a blank screen with the 'Sqldeveloper' title bar at the top. Have to close that down hard. If I wait 10-ish minutes, I can start the product up again. This seems odd.
