Query: Olympus C-5050 Viking "CARD ERROR"

I bought the Viking 512MB at a fair price (with manufac. rebate), but received "CARD ERROR" message on first use with my Olympus C-5050. This occured in 3 or 150 images taken at SHQ resolution (2.5 to 3.0 megabyte files). I like price, but now I am afraid to take this card on vacation for fear of corrupt images.I am planning to contact the manufacturer for a replacement.
