This bug sounds more like a server style error, I doubt it is your computer, but if you have something that could be altering your outgoing bandwidth (a dodgy router firewall for example) it is possible that the unblock message isn't sent to the server, however the odds of this are extremely implausible...
In either case Messenger Plus! is not causing this, and it is highly unlikely that your version of MSN Messenger is...could you please tell us what firewall you use, if you connect to the internet via a proxy or if you use a router?
