installed game map issues (whiting out)

[U124IXB]

This is Campaign Series forum. Seems you have issues with Panzer Campaigns?

Yeah in moscow 41 and kursk the map disapears when I click on it to get it to reappear I have to double click on it.
So I reinstalled the game same issue and I am getting  during install....."ISDX_ERR_INTERNAL"....."was not found in string"
Is my cd damaged is there a way around this?
Also when I patch the game I go to the about button on menu bar and check what version and it still says 1.0
but when I un-tick the box that says overwrite without prompting it always ask ok to overwrite file(s)
so that has me scratching my head too.Any way I really want to play moscow 41 again as well as kursk so if this is a cd issue should I by a old copy off ebay for 20$ or do the tiller games download for 40$? is there an advatage for either one thank you.
