Dear Bennett,

Thanks a lot for your reply. But then I don't know where the problem is. I have MIPAV v7.0.1 and the current JIST build (JIST-CRUISE-2013Apr24-11-36PM.jar), I follow to the letter the instructions here http://www.nitrc.org/plugins/mwiki/index... And, although I don't get a status box saying "The following plugins were successfully installed", when I restart MIPAV the plugins are installed. Then when I rebuild the library I get the message "Warning: Found 417 broken module(s). Do you want to delete them now?" and none of the modules under Algorithms show (although they are in the jist-lib folder). 

Regarding downloading other MIPAV versions, if you can download the file (v5.4.4) (and its size is not zero bytes), then I suppose it's "my" problem, I will try it from home. Another problem is that as here at the university I don't have administrator rights, I have to rely on IT to install/uninstall programs.

Regards,
Anna
