Yes it would. The blank screen + error noise generally means your modeldb file is borked. Although, if it gets to the medieval splash screen and then craps out, it means it's one of your data files like export_descr_unit.txt. Check the last two lines of your system.log.txt in your main medieval directory. If it says "unspecified error" then it's most likely in the modeldb file... If it's in one of the data files it will give you helpful information about which file and what line in the file.
