Help using IBM Migration Toolkit 2.0

Hello, my friends. I am trying to convert an sql file, exported from SQL Server, to Informix 11.10 pattern (I downloaded MTK media from IBM website - windows version). When I load the sql file, the screen hangs on section: Module: DBTreeExtensionSQL Message: Loading DB Tree. Use XMI file = false I´ve already waited for more than 1 hour, and nothing happens. The black screen on background shows several errors, like this: at com.ibm.mtk.translation.source.tsql.grammars.TsqlParser.pure_stmt_spa ce_list(TsqlParser.java:25936) at com.ibm.mtk.translation.source.tsql.grammars.TsqlParser.pure_stmt_spa ce_list(TsqlParser.java:25936) at com.ibm.mtk.translation.source.tsql.grammars.TsqlParser.pure_stmt_spa ce_list(TsqlParser.java:25936) at com.ibm.mtk.translation.source.tsql.grammars.TsqlParser.pure_stmt_spa ce_list(TsqlParser.java:25936) at com.ibm.mtk.translation.source.tsql.grammars.TsqlParser.pure_stmt_spa ce_list(TsqlParser.java:25936) What could be done? Is it hanging, really, or not? I´ve already checked all the prereqs, but I have all of them installed. Is there a newer MTK version? I even tryed to contact mtk through e-mail, but it turned back to me. Any help would be very appreciated. Regards!
