Hello ther,e

I have metastock EOD wtih reuters datalink datafeed, but the local files smbols are not updating.I mean the day to day data is updating. but many symbols that shoul dbe eliminated havent been. e.g. a symbol hasnt updated since feburary, when i check yahoo finance, I realized that that specific symbol is not valid. so How do I update that local symbol database?

Thanks.
