Launch box doesn't recognize Half-Life and Left 4 Dead

[LuWhisky]

Hello!

I'm trying to import Half-Life and Left 4 =Dead series to launchbox but it is not finding the metadatas. 

I've tried to change the names, the palaform from steam to windows but it didn't work.

How can I solve the problem?

Thank you!

Try highlighting Windows (next to Platform) and pressing Delete (aka remove the associated platform).  Then click Search for Metadata.  That should give you a list of platform options for Half-Life.  Select the last one (Windows).

If the options don't appear, you may need to refresh your local database.  Tools, Download, Force Update Games Database Metadata...
