I can't use VKMusic because every time I open it, it asks me for my email and password. I fill in both, but it asks me again and again. What can I do?
The VKMusic is free of charge and doesn't require any email or password to open it. In order to solve the problem, I suggest you uninstall the software using its uninstaller or Add or Remove Programs feature (Control Panel > Uninstall a program) and download and install a new copy from an official source.
