Importing lessons fails due to wrong reg ex

46~0~92~45;~45;~12~11~0~~B~~~~~~n~~;18;~"Wp_Eb"~~34~0~67900~0~0~~21700,45~0~92~45;~45;~0~0~19000~~~~~~~~n~~;18;~"Wp_Eb"~~34~0~67900~0~0~~0 is not correctly parsed into 46~0~92~45;~45;~12~11~0~~B~~~~~~n~~;18;~"Wp_Eb"~~34~0~67900~0~0~~21700 and 45~0~92~45;~45;~0~0~19000~~~~~~~~n~~;18;~"Wp_Eb"~~34~0~67900~0~0~~0 but in much shorter parts.

The correct reg ex would be ((?:\"[^\"]+\"|[^,\"]+)*),?.
