If you have white PDF, it can be problem also of your logo. Please, check what type of image do you use in VirtueMart. VM Invoice with TCPDF library should work with JPEG and non-animated GIF. PNG can be problematic.
Those language files with errors are modified or original?

For sure, do you have installed Adobe Reader plugin in your browser?

Already uninstalled, but still not working on Firefox.
I've tried Chrome and it works like a charm.
