thanks, I was under the impression from the jempeg.org page that it only went up to 44 or 45. And when jemplode goes to update, it tries to 'update' my v45 with v44.

I dont relaly know how to upgrade this, I used the windows installer (.exe) originally. I replaced the jemplode.jar in c:\program files\jemplode\lib\ with the new jemplode.jar, but now it wont run, it says:
