I can't get them to sync.
Any tips?

They don't as of right now. Should be in a later build

If I go to "Add Channel", "Add Own Channel", there's an option called "Add Aggregator (Google Reader, Blogline...)", except it won't accept my details.

I just added Google reader and it worked fine. What version are you using? Mine is build 3.0.111 Platform 4.2.0 (options>about).

Have you tried adding the aggregator on the Viigo website?

Works nice, however I think if you add any new feeds to Google Reader, you have to go to Viigo, delete the Aggregator and re-add it.

I added google reader to my viigo. Worked just fine but now I can not delete or remove unwanted channels from the google aggragate on my BB viigo. I did remove them from the google reader but the unwanted channels are still my viigo.

When I click on menu while viigo is open, the remove channel is not there.

Any suggestions?

As was alluded to above, I tend to have more success by working through my viigo.com site on my PC

Thanks akosnitzky,
I went to viigo web site, deleted the entire google aggragator, updated what I wanted from google and added the google aggragator back into my viigo.

Thanks for recommending the viigo site to make the changes.. it worked.
