Problem with MSC mode

Please help me with my Sansa Clip player. I want to view and edit my music files in MSC mode, but its not working!!
I have my player already half year and allways used it in MSC. Yesterday I buy a new computer (with Vista) and now when I connect my Sansa in MSC mode I get an error. Its mean that its recognized like “new usb mass storage device”, but! When I want to explore my files it took to computer a long time to try to open this “removable disc” and in the end I get error message (see picture). In MTP mode it works fine but I dont like it. After reset it still get error.

it has v01.01.18f version
