I see an error message and don't know what to do.
Error messages often contain “What to do?”-like link to a page with detailed information on fixing the issue. This information is often sufficient, so there's no need to contact support. If an error message doesn't contain a link, then, as a rule, the message itself contains information on fixing this error. If you tried everything in instruction on fixing an issue, but had no effect, send us a bug report right from the application after an error message appeared.
