Hi Juan Pablo,
I am not very IT-minded! But I have made some suggestions:
My first formal letter
NOTE: I hope that you can help me with corrections and suggestions about the wording :)
Dear Mr. Smith
I need some technical support for the Acme equipment we have, and I hope that you can help me. My problem is with the Pocket? that does not recognize the device we want to use.
(in this case the Acme instrument)?
The pocket operating system is Windows mobile, and I think that for this device we need to install drivers so we can accurately measure its performance. Using Acme software for laptops (Windows 8) is not the issue, it is just the Pocket that we are having some problems with.
I would appreciate any help you can give us regarding this issue.
Yours sincerely
Juan Pablo Rey
