Problem with Export from Eclipse to Centrasite

We have a project with SO v32 that uses a File Event. When we try to Export the project to Centrasite (v2.2) we get the following:

Add Resources into Centrasite: Successful
Register Resources into Centrasite: Successful
Start Project Resources: Unsuccessful

In the detail of the message it says:

Unable to load project descriptor
Cannot find copy of .projectdescriptor in repository. Make sure it is present in the repository
Unable to get resource information cTaxBalances/hdcWactolSequence.fileevent
com.softwareag.xbridge.portals.PortalException: embedded exception: com.softwareag.xbridge.repository.NoSuchElementException Can not find copy of hdcWactolSequence.fileevent in repository. Make sure it is present in the repository.

We have checked CentraSite and all the resources appear to be present.
Looking through various log files does not reveal anything except for the CentraSite Apache access.log which shows the following messages:

This is on a customers machine but when we try it on our own machines using the same versions of the products we do not get any problems.

Can anyone provide some advice as to why we are getting this problem and how to resolve it please?
