I am getting an error with 1 category when I import into j2.5 using flexi migrate 1.1. The import also hangs on "Import releases datas":

Is there a way to identify which category is failing?
Here is the full steps of what I did:
1) Installed Fleximigate 1.1 onto Joomla 1.5 site. Generated the fleximigrate.zip archive without problems.
2) Created a completely clean Joomla 2.5.9 install
3) Installed com_flexicontent_v2.0_RC9b_r1601.zip
- Performed preconfiguration tasks.
- Opened + Saved the configuation screen
4) Installed Fleximigrate 1.1
- Created a directory /images/fleximigrate and moved fleximigrate.zip into it
- Launched the import
