Problems while generating code with SubStage / Subsonic (Hangs on generating structs)

Question

I have an old project and it uses Subsonic for DB access. I tried to regenerate the code for tables, etc... I tried using SubStage (I used 2.1 because the "old" code is using this version as well).

It seems to work fine until it hits the "generating structs...". It just hangs there. I didn't find any log to help me find the problem. I let it run for 10-15 minutes and I had to "kill it".

Is there any log I could check somewhere to find the problem? Should I use something else to regenerate the classes?

Thanks!

UPDATE: It works if I exclude all stored proc. If I add just one (no mater which one), it doesn't work.
