How are you entering your anchor texts? Manually with html or automatically in the wizard? As said before, always check spin preview before posting, and click on the anchor text to make sure the links are added properly. You can also go into the URLs tab to make sure that your URls and anchors have been entered properly.
Definitely SB the senuke backlinks, forum profiles would be ok as well.
The senuke forum is ok for support - I've learnt most of my senuke stuff from pobman's forum ...> its now at zontseo. I think he's a member here as well. He's got great templates and videos explaining how to use the templates. I love using senuke to build backlinks to my manually created web2 properties, and some of the templates on his site are awesome (check out the penguin food template!). There's a monthly sub to get the templates, but if you want to learn how to use senuke properly, then definitely recommend this site!
good luck
