Hello world !

First, sorry for my bad english

It's been two upgrades where something wrong happened on my machine.
Same way for the two...

On starting my computer, I received a message in a window stating I should install the latest version of Messenger Plus! Live (or my Messenger Plus! could be no more useful).
I clicked on the button to install the upgrade, WLM was shut off, the "upgrade" installed and... I had no more Messenger Plus! active on my machine. Nothing! All was gone (although the directory had been emptied and filled again with (new?) files).

It seems that the files were copied on my machine, but the connection with WLM was not activated properly.
If I install Messenger Plus! Live directly from the web site, there's no problem.

Configuration : computer assembled for me :
motherboard EPOX 8KDA3I
processor Sempron 3100+
RAM 2 GB
2 HD - 8 partitions - single OS
Windows XP SP3 French
Windows Live Messenger 2009 (14.0.8064.206)
Messenger Plus! Live 4.82.368 (last version) installed in the default directory but it happened also with previous version (4.81 from march 2009)

Did anybody experiment the same thing ?
Did I make something wrong ?

Regards,
