Period Converter - Forgot to check DLL, how to change chart properties

Help please! I’m familiar with Period Converter, but in creating a new chart I unfortunately forgot to check DLL, how can I get the properties of the resulting (offline) chart changed/updated to specify DLL?

What I’ve tried includes deleting the chart, restarting MT4, re-invoking Period Converter (making sure I check DLL) and the deflective chart that doesn’t update the market data (for lack of DLL) is still there - any suggestions?

PS- Are these Period Converter charts stored somewhere where I could go in and manually delete a specific chart file? Thanks!
