Check in Drawings to Vault

Hi

We have a machine running Solidworks Office and I was wondering howto use the PDMWorkgroup add-in?

At the moment, I can check out drawings for the vault but I havenot been able to work out how to check files back into the vault.

I was told by my VAR that you need to upgrade your license - butsurely this is stupid if I can only check out files but not in? Whygive the ability to check out only?

Can someone help me out here?
