Think I fixed the Skype problem. Somehow I got logged on on my laptop and so that must have disconnected the connection on the N900.

Checked to make sure I wasn't also logged on on msn on laptop but I am not so that does not explain the msn N900 problem. I deleted the Testing Catalogue after I installed the plug in as people say opening device to Testing could cause problem. Could the absence of the Catalogue be the problem? i.e you have to have the Catalogue available on your device in other for any apps installed from that catalogue to function properly.
