problems with OSCAM 1.20-unstable_svn ****

Hi

I'm currently using oscam to read my card (0963), been using it for a while, since yesterday rev 7311, 12 & 13, been getting these errors

If I revert to 1.10 or earlier versions of 1.20 the card works fine, anyone any ideas

TIA

thanks for the reply, any ideas which is the most stable version of 1.20 to use
