[Plugin: WordPress Download Monitor] Showing wrong dates

I love this download and recently upgraded to the latest version thru the “automatic update” (version 3.1)on one of my sites. However, since doing so, it now shows everything new I add with the same wrong date — Jan 1st, 1970 ??? Do we have a bug here? Server date and all other posting dates etc are correct… just the DL plugin showing the wrong date… I had to go into the database and change it there to get it correct. This is such a great plugin and this is the first problem I’ve ever had with it. ???
