For some reason I cannot run Trados. Instead of opening as normal I get the error message:

hexadecimal value 0x00 is an invalid character. line 1, position 1.

I have tried repairing the programme and I have uninstalled and reinstalled it and I am still having the same problem.

Any ideas?

delete the following file Aug 22, 2012

try deleting the following file:


C:\Users\\AppData\Roaming\SDL\SDL Trados Studio\\plugincache.xml

it will be recreated when opening Studio again.

(you will have to unhide the files in Folder Options before you can find it.
for Studio 2011, the filepath is very similar).

good luck!
