Error Activating Solution - Solution cannot be read

Starting Servoy this morning and no Active Solution but the forms I was working on last night are still visible albeit completely filled with warning symbols on every line. I tried to activate my current solution and this failed. see screen shot. Any help or advice would be appreciated. Version is 7.2

Hello Stuart,

I doubt you might have any solution in workspace with lower file version number that supported in 7.2.

Can you please check rootmetadat.obj file for every solution in workspace to and check if the fileVersion number is correct.
I believe for 7.2 the version number is 43.

Hope this helps.
