Version 0.1 of Recapture and WordPress 2.5 do not mix. I apologize for taking so long to announce this, and for being so slow to produce a remedy for this problem. For now, please use the development version of Recapture which seems to be working fine with WordPress 2.5.

After this semester ends (in three weeks) I will be able to devote more time to making a newer version. In the meantime, test out the development version and let me know if you discover any bugs. If there are any developers out there that would like to help out with making Recapture look prettier and / or function better, please let me know.
Also, parts of the current development version are courtesy of Josh Moles. Thanks Josh!
