I upgraded to newer version of Winbox and all of sudden I cannot log in.
I was advised to go for the earlier version.
I keep getting missing roteros.dll message.

How can I fix this problem please?

If you can find the 'roteros.dll' file in the old version, copy it to the correct location in the new version. It might be present in the new version in a wrong location. Read every instruction that comes with the new version: there may be changes to the folder structures to note.

Well, not sure where to start looking.
I have deleted the current version and downloaded the old version. No solution yet

Check if this can help. Google for similar problems and observe how they solved the problems. I've not used winbox so I don't really know much.

I have searched but the solutions I have seen are not tenable.
I downloaded from the link before but was too scared to try installing it.

Will try again tomorrow. Tankio
