Not familiar with those mods from Hawkeye, but with regards to OvGME - make sure that the file(s) you are trying to use have the correct file structure in the zip. Sometimes the initial sub folder may be duplicated twice.
Also ensure that, in your case OvGME, is pointing to the correct location in DCS (detailed in the readme).
(I may not be using the correct terminology, but in my case, sometimes when you actually unzip the file, the first folder is named the same as the next underneath - which ‘can’ confuse things like OvGME, or the one that I use - JSGME).
Hope your issue gets resolved soon.
