Dancing Stage Party Edition problems

[Rock Ape]

Recently bought 2 copies of Dancing Stage Party Edition and Logix 3 dance mats for PSOne. Both CDs give us the same problem. the basic Game Mode works OK but on selecting Lesson Mode and Training Mode we get a "Now Loading" message that eventually times out. We are new to PSOne, but this problem occurs consistently. Is it looking for a file that's not on the CD? I added a memory card but that doesn't help. Any ideas anyone.

By the way, the 75p/min help line does not even quote the game in the options on the automated switchboard. I find it appalling that the authors of the software don't have a tech support/helpdesk or even an FAQ section on their website, and apparently no way of contacting them other than snail mail. Excellent customer care.
