SageForum for UK versions of Sage 50- Help and support.

We have a small homebased office and recently set up a peer to peer network. While doing this, Sage started having problems, and we were unable to open it. We uninstalled everthing on the computer and then reinstalled all the programs. I am now unable to upen sage on my pc, and sometimes have problems on the other pc. There are also other complications, e.g. when we open a customers account it shows no invoices in the activity section. I would be so grateful if someont could offer me some help or advise.

What operating systems are you using, what version of Sage, how many user licences, is "check data" reporting any errors?.
