[NTG-context] Problems with new beta

Just installed the new beta. Now every run of texexec dies with lots of messages like this: kpathsea: Running mktexmf ec-lmcsc10 ! I can't find file `ec-lmcsc10'. <*> ...four; mag:=1; nonstopmode; input ec-lmcsc10 Please type another input file name ! Emergency stop. <*> ...four; mag:=1; nonstopmode; input ec-lmcsc10 Transcript written on mfput.log. grep: ec-lmcsc10.log: No such file or directory What gives? Thomas
