Well that's a pretty un-explanatory notice, by that I mean it's not really helpful. You might want to take a look in the SP error log in Toolbox from the admin menu. Ignore notices, just look for errors and hopefully you will find further explanation.

However, please bare in mind this forum is really for pre-purchase queries. If you require further help please take the question to our support forums.

Good news, thanks for letting us know.
