Icons for 5.1 on Vista 64

[Hahaiah]

I'm running vista 64 and installed Textpad 5.10 over 4.7 and my icons for Txt files are messed up, not to default notepad, but the "unknown" icon

I tried entering this in the registry, but it didn't help

C:\Program Files (x86)\TextPad 5\TextPad.exe,0


Is there a quick fix for this ?

I should have uninstalled the old one first I guess, but didn't wanna lose the settings

THanks
