java error in SOPC builder

hi,everyone.Recently I run into a problem when using SOPC_builder. When I add a new .ptf (DE1's SRAM Control IP)into the SOPC system,it showed that Messagebox"An unexpected error occurred during Loading HDL Component:java.lang.nullpointerexception".May someone tell me what's wrong with Sopc_builder?Is the promblem result from QuartuesII(ver 9.1)or the SRAM ptf? PS:my OS is windows 7?thank you for replying~

    Hi, this reply comes probably too late to help you in any way, but this might be useful for people googling nullpointerexception and sopc builder so I decided to answer anyway.

    Problem might be that some of the files/folders sopc builder is using are read-only. I'm not sure which but I solved similar type of problem with just removing read-only attribute from all files/folders on my project.
