Sage 50 Accounts - May Update Report Designer Issue

SUGGESTED

I installed the update today and since then I can't access my layouts/email reports. 

Messages -

'The specified data source SageLine 50 v13 could not be found' (I'm on v23) Check that the data source is correctly registered'

I'm the sole user and Program/Data/Settings Directories are all C:// - all the help articles seem to point to installs in the wrong directory but this is where everything should be for me. Has anyone else encountered this?

Thanks!
