Could not load type '' (blank) error when trying to reference .NET assembly in NAV2013

I've created an assembly that I want to be able to call from C/SIDE in the Role-Tailored Client in Dynamics NAV2013.

I've got this all working locally but when trying to deploy to the server I can't compile the codeunit that references the .NET assembly

I have a variable of type DotNet but when trying to choose a subtype I get this error:

Could not load type '' <-- nothing between the single quotes!

I've followed all steps in the MSDN guide (save exporting the types I want to use) I've got this working locally. I can actually get it running by installing the assembly into the GAC, but I don't want to have to do this when it should work otherwise

(the add in is also registered in the Client Add-in table and is strong-named with the correct public key token in the table)

These are the things I've tried:

All the assembly does is calls out to some webservices and a couple of other things, I just can't work out why I can't get it to work

I suspect it's permission related since installing to GAC seems to make it happy

Any ideas?

Thanks in advance

Turned out to be Windows Server 2008R2 security feature which blocks dlls when copied from another machine

I unblocked it and all is well!
