Hi, thanks for posting. This is a BuddyPress limitation rather than Welcome Pack; I expect you have exactly the same issue around all BuddyPress links around your site?
Hi Paul,
thanks for response. At the moment it seems that only Activation Link does not work. You can test it at http://www.unitedcasting.de
At the moment I’ve problems with Groups and Forums. I can write in each group or forum. I write a post in Forums and choose a Group to publish. In Groups I can read, in Forums not, if I logged in. When I logged off, it works fine, see

Maybe an error of the theme or of BP?
If you’ve got your htaccess file (or equivalent) rewriting the URL to prefix everything with “index.php”, I’m not sure why it doesn’t work with the activation link.
If you disable Welcome Pack, and register a new user, does the problem remain?
I disabled the Welcome Pack and registered a user, but the problem is still the same. I do not have htaccess file because I use Windows 2003 server. Which is the equivalent file?
Now it works!
It has to do with the mod-rewrite Code on IIS 6.
I used the recommendation of
http://www.kylecaulfield.com/permalink-for-wordpress-iis-6-mod_rewrite-fixed-free
and put in httpd.conf file this
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?p=$1 [NC,L]
but it’s better to use that
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule .* /index.php [L]
And now it works!
Thanks for the right idea at the right moment.It will help me a lot.
what about for linux?
Am having the same issues here….
What about Linux? The post is 7 months old. What problem are you having 
Hey Paul,
I get the activation key email sent, only to get the message “Please provide a valid activation key.” when i click on the link.
The account in the meantime was activated by itself it seems.
Can you confirm that the account is definitely disabled BEFORE you click the link in the email (try logging in, does it let you?)
