Can't get My "Iron Robot A" plugin for UE to animate in Sequencer anymore

Hi Everybody, I purchased this fantastic little Plugin called “Iron Robot A” and have used it a couple of times quite successfully in UE via the Sequencer, but now when I add the Plugin to my project, and drag the Robot Mesh into sequencer, when I hit on the +Animation Button, like I’ve done previously and the small window appears with a list of all the animations available, like…Idle, Walk, Run, Jump etc, now when I hit on the +Animation Button, it tells me !No Animations Available, even though they are still in the Animations Folder of the plugin itself, and if you Double Click on them from there they open up and play just fine, I have checked my filter settings and everything looks fine and I have checked the settings in the Details Panel, where things could be out of kilter, but it seems to be Okay. If anyone could offer any assistance or pointers, I would really appreciate it, like I said I got this Robot Running and Jumping around in my scene previously. Many Thanks, VC.
