BaseObject altered exception

There is a single page on my XWiki installation that can't seem to be rendered. I can't delete it, access it, anything. Here's the exception: Error number 3202 in 3: Exception while reading document XWiki.msmctreeatusibmcom Wrapped Exception: Error number 3212 in 3: Exception while loading object XWiki.msmctreeatusibmcom Wrapped Exception: identifier of an instance of com.xpn.xwiki.objects.BaseObject altered from -43849225 to 291881179 com.xpn.xwiki.XWikiException: Error number 3202 in 3: Exception while reading document XWiki.msmctreeatusibmcom Wrapped Exception: Error number 3212 in 3: Exception while loading object XWiki.msmctreeatusibmcom Wrapped Exception: identifier of an instance of com.xpn.xwiki.objects.BaseObject altered from -43849225 to 291881179 at com.xpn.xwiki.store.XWikiHibernateStore.loadXWikiDoc(XWikiHibernateStore.java:646) at com.xpn.xwiki.store.XWikiCacheStore.loadXWikiDoc(XWikiCacheStore.java(Compiled Code)) at com.xpn.xwiki.XWiki.getDocument(XWiki.java(Inlined Compiled Code)) at com.xpn.xwiki.XWiki.getDocument(XWiki.java(Compiled Code)) at com.xpn.xwiki.XWiki.getDocumentFromPath(XWiki.java:637) at com.xpn.xwiki.XWiki.prepareDocuments(XWiki.java:2428) at com.xpn.xwiki.web.ViewEditAction.execute(ViewEditAction.java:133) at org.apache.struts.action.RequestProcessor.processActionPerform(RequestProcessor.java:421) at org.apache.struts.action.RequestProcessor.process(RequestProcessor.java:226) at org.apache.struts.action.ActionServlet.process(ActionServlet.java:1164) at org.apache.struts.action.ActionServlet.doGet(ActionServlet.java:397) at javax.servlet.http.HttpServlet.service(HttpServlet.java:689) shawn lauzon.
