I'm setting up PDI on a new pc, and am having a problem loading Marketplace plugins.

This is PDI 5.3 CE, on Windows 64 bit. java version
PDI is in C:\Program Files\data-integration\

PDI seems to start normally, but I get an error message when I try to add something from the Marketplace.
Any suggestions?
Thank you!
