Error in 4.02

[Skybird74]

If all your files are in kma format, why would you need to re-import? It sounds like you are just having problems with the program. Your kma files should still be in tact. What Hoster version did you use before upgrading to 4.xx? If all the upgraded versions will not play your files, including 3.4, then I would suggest using 3.321 or whatever you had before you upgraded. At least you'll be ready by tomorrow.
From what I have read on the Posts, you may want to wait for 4.03 to come out, like I'm doing. It is supposed to correct all problems reported by users.
