Hmm.. could be a file write permission error?

BTW:
What the hell is in the CDS table definition (`discid` varchar(Cool NOT NULL, ..) ?

hmm very strange - i restarted - still same problems but this time i used orginal mysql5 query tool and cdtracks table now produces same error - i don't understand this. :/

Ps. the cool is made from orion out of - originally

ahh i found the bug, i'm so silly!
Its a incompatible data type length for foreign key submitterid, in table submitters and table cds.. now it works.

Btw. it would be impossible that it worked for you then ?

Something else, i know quite noob but- what does the number for in bracktes behind the integer data typ define .. the number of bytes or the number of digits that is allowed to have max?
eg. `cdid` bigint(20) unsigned NOT NULL,
I expect about 8.000.000 entries, so i am not sure if i have to take as big values in ddt i did!

Number of digits
