Getting 403 when trying to release updated jar

Though I've been able to use the oss.sonatype.org site to release my jar's to Maven, all of a sudden I get a forbidden (403) dialog when attempting to release what I've uploaded. My user id is wnmills3 and the project is com.ibm.jsonata4java

Is it possible to update my account so that it is viable again? I can log in but I can't release the jar file.
