Magento

I got the following when trying to upload products using dataflow:

* Starting profile execution, please wait…
* Warning: Please don’t close window during importing/exporting data

* Starting Mage_Dataflow_Model_Convert_Parser_Csv :: parse
* Found 3553 rows
* Starting catalog/convert_adapter_product :: parse

I have uploaded products using dataflow before, and when it messed up I would get an error or if it was successful, I would get some sort of indication it was finished.  now I’m just getting this and I have no idea what the problem might be.  any thoughts?

Thanks!
