FRD Freeze on Startup (4 replies)

It all started when I put a link to more than 7000 image
only I do not want to lose the old links that I had not downloaded
how do I fix it? without losing the other links I've ever had before?

anyone have another solution? already I tried to install the new version of java
download frd again

here the error
