Cant send attachments?

after uninstalling i.e 7 beta on my p.c i cant send mail attachments,it just says"invalid file"but im only using jpeg and ive followed yhe instructions to the letter

how can you restore your settings or is there any way to get attachments working again

p.s i can use my other machine if i need to,and the computer in question is going in for repair(new hard drive)in a month so its not the end of the world,but i would like to know for now and future reference

thank you

Try installing I.E again, not the beta version.
