mojza|||Thanks, I was able to solve the problem.

There was some dll's missing in the repository folder once I copied them over and register the files I was able to get rid of that problem.

However another problem developed which is once I click on a dts package to open up it just hang with only white space. I check to see if all of the dll's for the dts package was there, which it is. Doesn't any one know what this problem is?

Thanks
