I know the topic is over an year old, but the problem is still not solved. After a clean install of one of out PCs there is a conflict between ecatcher and sophos (basically almost anything, based on OpenVPN). If I install the ecatcher tap adapter - it overwrites the sophos’s one and vice versa. Years ago I managed somehow to make the both programs live on the same PC, but I cannot remember how.
But, if you sell a device for 700+ Euro (which, I think is based mainly on open source software) you should at least take the effort to make it right! FYI there are competitors in east Europe, which sell similar routers for a fraction of the price and they work pretty well (personal experience, ewon was my boss’s choice)!!!
