Could not fix performance issues. Connection is off-line

Hello Phil.
Could you please let us know whether you have installed the trial version of the AVG PC TuneUp program on your PC? If so please check whether the trial version of the program hasn't expired. If the program has expired it is to keep you informed that you could only analyze the error's and couldn't be fixed using the free version. Please feel free to contact us for further assistance.
Thank you.

Hi all,
Have just reinstalled AVG free.Noticed that there is a performance analyser.
Set it running and it reports lots of errors.
Clicked the Install to Fix button and it reports Could not fix performance issues. Connection is off-line.
Followed the link to learn more, but can't actually see how to install and fix the errors.
Any help gratefully received.
Phil
