Miranda Portable + Ping Plugin = Miranda doesn't start...

I have Miranda Portable 0.7.17 (latest) and I tried to use Ping Plugin 0.8.0.2 (latest) with it. However after putting pingplug.dll in the Plugins folder Miranda doesn't show in the taskbar. I have to kill its process. After deleting plugin's dll everything is back to normal. I don't have this problem with other plugins and portable version of Miranda.

Can anyone check if Ping Plugin works with portable Miranda?
Thank you very much in advance.
