DATTool and DAT Compression

I've recently tried my hand at a few class tweaks using Temple+'s new DAT files. While I've been able to extract the files with Zanes, DATTool keeps giving me an application error (0xc000005) when I've tried to use it to build new .dat files. I've followed all the instructions in the manual, including adding the appropriate folders as well as the tio and zlib dll files but it still doesn't work. Is there a solution for this or another method of creating DAT files? I'm using Windows 7 64-bit version if that helps.

 

I had the same problem

 

Attached is what I use for compression, including the DLLs (it's possible that the GoG tio.dll is necessary, don't quite remember).

 

Thanks Sitra, it worked perfectly.
