Deluge scripting failure

Hi support team,
In july, I wrote a deluge script using apitite Creator-CRM library from the market place. The purpose is to retrieve a few records from a CRM custom view and populate a table in creator for reporting purpose.
Everything was working fine in July, but it appears now nothing works anymore for no reason. After half a day trying to understand what was going on, deleting script parts in order to pinpoint the issue, upgraded to the latest apitite version, I tried to follow the running script using inserted info statements. After another half day, I give up as it seems the script stops for no reason, not always at the same place. It looks as if it is unstable and crashes at some point during XML decoding process. There is no message
This is a critical problem for me as my customer for whom the script has been created is waiting for its delivery.
What can you do for me ?
Best regards,
