Can someone help with the hangman code?

i'm trying to make a hangman game yet i'm getting errors in these parts:
System.Text.RegularExpressions.Regex.ism...rgx, that it is not part of system .text and also the rgx bit is claiming to need a '<' for an xml tag. can someone help me with those errors and quickly run it on their vb please? this is because i do not have vb on my computer. thanks in anticipation
