Hi
had itunes installed (windows vista 64), after lots of errors and refusing to sync nor repair nor upgrade - I uninstalled. the next step was that it didnt want to reinstall due to older version... have now removed all with Revo uninstaller pro. Now i cant re install as it tells me I dont have enough space even though i have 80gig open? dont know what else to try.

Best to remove all music and re-sync from the Mac, which you can do without doing a complete Restore of the iPhone.  Assuming that you auto-sync music and not manually manage music on the iPhone:
While connected to your Mac iTunes, change your sync settings by un-checking the "Sync Music" option, then apply the change to delete all the music.
Since there seems to be some funny business with iCloud, where some music downloads stubbornly remain on the iPhone despite attempts to delete them, disconnect from iTunes and check your iPhone to make sure all music really was removed.  If you still see music, first turn off the "Show All Music" option (Settings/Music/Show All Music/OFF) since songs with a cloud symbol really aren't on the device.  If after doing that you still see music on the iPhone, go to Settings/General/Usage/Music and swipe left to right across "All Music" and tap Delete.  Hopefully that deletes past cloud downloads you may have done.  If not, I've had to change to manual sync mode, manually deleting remaining songs by navigating into iPhone via iTunes, backing up, restoring from backup, then changing back to auto-sync mode.
Re-connect back to iTunes and change your sync settings to allow music syncing -- either your entire library, or selected playlists, genres, albums, etc. 
You mentioned that your library is "only 14 GB" but consider that if you have a 16 GB iPhone you don't really have 16 GB of storage, so perhaps you're running up against a real capacity issue if you own a 16 GB model, or have a larger model but other things taking up space.  So perhaps you can no longer sync your entire library as you expect.
