Custom game -only 1 broken card : mox opal

My version of Mox Opal is broken in my custom version and only in my custom version. And it is the only broken card in my custom set.
In constructed version, it works fine. But in Custom version, it only allows me to produce 1 black mana. There is also only 1 black band over the card. (It could mean that its card information may be broken, but not sure).
What I have already tried :
removed it from my custom version using My2000 and/or CustomSetEditor. Closed My2000. Then put mox opal again in my constructed version with My2000.
Modified the information set editing ManalingC.csv and Manalink.csv, but those lines are the same in the two files.
used an other update to patch my custom version (I don't k,ow if it relevant)
tried to install camelbox, but it only allows me to install in c:/ directory and I don't have any C:/ directory, only j:/....
Is there any easy solution to fix that by myself ?
Thank you very much.
