shop configuration not possble

[Ceesdu]

Hi,

I have installed Joomlart CAGOX in XAMPP version Win 32 1.8.3-5 VC 11 installer. On windows 7 Ultimate SP1

When I go to SHOP for the configuration is it not possible to change anything, I haven't Change anything in Joomla or virtuemart. I get this warning

WARNING

JUser.: load Unable to load user with ID: 1
JUser.: load Unable to load user with ID: 315

There are no users with those ID's

vmError: : Safe failed with following error: Username in use.

I have send this also to Joomlart and get this from them:

These errors came from Joomla! core and VM.

# First error because these users, which one VM tried to load are not exists.
# Second error because VM tried to save user with username already existed.
( and that's why i said please go with VM forum ).

Explain about this issue.
It's because sample database and VM.
To fix it.
Just clean VM database by tool provided by VM
Where can I find that tool?

Kind regards Cees

This is the problem with quickstarters not correctly prepared for vm. For the tools, please read the docs. http://docs.virtuemart.net/manual/tools-menu/70-tools-migration.html
