I got this recent problem with ZC. It has this "error can't open", and I found out how to fix it, by redownloading ZC, BUT then everytime I turn off the PC, it doesn't work..I tried 183 it worked, but snice it's DOS, I couldn't use it agian. 163 worked, but then it keeped turn off. Note:My PC is very fast, and has XP, so it can't be because it's old. If there is another "NEW like ZC version, I would try it.( like 193 old). Is there anything I can do? 😕
